SHOCKER NXT
Operation and adjustment instructions

Q U I C K START
01

The SHOCKER NXT can be damaged by liquid CO2. Thoroughly
read and understand the Gasses Section of the manual before
using CO2 to avoid damage.

BATTERY

LOADER
Insert your loader into the feedneck and make sure it is secure.
Due to the high rates of fire that
Shocker NXT can achieve, we
recommend the use of a modern
high-performance loader.

Have your compressed air
(HPA) or CO2 tank filled by
a person who is properly
trained to do so. If using an
HPA system with an on/off
valve, such as the Max-Flo
or Max-Flo Micro, make sure
it is in the OFF position. If
using a screw-in style preset
HPA tank, or CO2 tank, an
ASA with a built in on/off
valve is recommended.

TURN ON AIR
Gently gas up the Shocker NXT
by slowly turning on the air
system or ASA’s on/off valve,
or slowly screwing the CO2 or
compressed air system into
the ASA.
A gentle rise in pressure is
important, as a sudden blast
may reduce the service life of
the Shocker NXT’s internals.

FILL TANK

Screw the included barrel
into the Shocker NXT. Put
the supplied barrel blocker
over the end of the barrel,
securing its cord as far
back on the Shocker NXT
body as possible, and
cinching it tight.

Using a 5/64-inch Allen wrench,
remove the two screws from
the left side of the rubber grip,
and lift the panel open. Attach
a fresh 9-volt alkaline battery
to the battery clip. Position the
battery in the grip frame, tucking
the battery wires into the space
above the battery. Close the grip
and reinstall the screws.

BARREL BLOCKER

TURN ON SHOCKER
Turn on the Shocker NXT by
holding the power button down
for approximately 1 second. The
Shocker NXT will chirp and the
power button will glow continuously to show that it is on and
in Vision mode. If you need to
disable Vision mode to fire gas
without paint, push the button
once again, and the power
button will blink in a double-tap
sequence. Press and hold the
power button for approximately
2 seconds to turn the Shocker
NXT off, this acts as an electronic safety.

ADJUST VELOCITY
Fill the loader with paint and turn it on. While wearing ASTM compliant paintball goggles in an area where all bystanders are protected, remove the barrel blocker and fire over a
chronograph to measure the velocity. Using a 3/32-inch Allen wrench, loosen the velocity lock screw near the bottom of the vertical regulator and adjust it with a 5/8-inch open-end
wrench or adjustable wrench. Turn clockwise to increase velocity/pressure, and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the gas
pressure inside the Shocker NXT to stabilize. Adjust until the Shocker NXT is firing consistently within the limits for the field where you are playing (for safety reasons, never adjust
the Shocker NXT to fire at greater than 300 feet per second.) As you adjust, check the Shocker NXT’s pressure gauge to be certain you stay within the Shocker NXT’s operating
limits of 180 to 220 psi. Lock the velocity setting by tightening the velocity lock screw. Depending on what modes of fire are allowed at the field where you are playing (semi-automatic, rebound, etc.) you may need to adjust the Shocker NXT’s Rebound setting. See the Rebound Adjustment section for more information. Shoot out the competition, hang the

The Shocker NXT has been designed with
simplicity in mind so that you can concentrate on your game instead of your
marker. It has a minimal number of moving
parts and seals so that you can maintain
the marker with little effort. This DOES
NOT mean that you should neglect your
Shocker NXT. If you take care of it off the
field, your Shocker NXT will take care of
you on the field. For best performance,
clean and grease your Shocker NXT frequently. Many players clean their Shockers after every use. While this may seem
a bit extreme, being vigilant in the upkeep
of your Shocker NXT will extend its useful life considerably. Playing in the rain will
not damage your Shocker NXT, but you
should NEVER immerse it in water. If your
Shocker NXT should become waterlogged,
remove the barrel and rubber grips and
allow it to dry out, then follow the disassembly instructions for full cleaning. Clean
out mud and paint with a damp cloth and
alcohol. Grease the Shocker NXT ONLY
with SL33K pneumatic grease. Use high
quality paintballs.

BARREL BLOCKER

PLEASE READ CAREFULLY

FIG. 1

BARREL BLOCKER IN USE

FIG. 2

USE HIGH PERFORMANCE LOADER

The Barrel Blocking Device is a critical piece of paintball safety equipment - nearly as important as
paintball goggles. The Barrel Blocker serves to protect against accidental discharge of a paintball
by catching it before it can cause harm. A Barrel Blocker is included with the Shocker NXT and must
be used every time it is handled in an area where people or property are not properly protected by
paintball goggles or paintball field netting. To use the Barrel Blocker simply slip it over the end of the
barrel and stretch its cord back over the back of the Shocker NXT’s gripper (the extension on the
back of the body) or the rearmost part over which it can be securely looped. Use the strap’s adjuster
to cinch the strap tight, so that the Barrel Blocker can provide protection against accidental discharge
of a paintball.
The Barrel Blocker should only be removed when the Shocker NXT is on a “live” paintball field and all
persons involved are wearing proper paintball protection.
HOPPER
The Shocker NXT is a high performance tournament grade paintball marker. The break-beam Vision
system means that you won’t need to worry about chopping paint because your trigger finger is faster
than your hopper. However, if you want to realize the Shocker NXT’s maximum firepower potential,
you will need to use a high performance loader. High performance loaders, especially those which
provide force-feeding, will yield the best results with the Shocker NXT.
Depending on the dimensions of your hopper you may choose to remove one or more of the friction
o-rings from inside the Shocker NXT’s feed tube, and or to sand down the hopper’s feed neck. The fit
should be snug, but not excessively tight. Always twist hoppers clockwise when installing or removing, to avoid unscrewing the feedtube from the Shocker NXT body.

Never put oil in a compressed air regulator or tank—only
apply manufacturer specified lubricants.

GASES

FIG. 3

The Shocker NXT is a low-pressure paintgun. It operates in the range of 180 to 220 psi, which means it
can function well with either compressed air or CO2 as a power source. Proper set up of your gas system will help you obtain the best possible performance from your Shocker NXT.
High Pressure Air systems (HPA) are the most common power source used with the Shocker NXT, as
they are unaffected by temperature fluctuations and do not have the potential for liquid problems. HPA
systems consist of a tank and a regulator, and are typically rated to store air or nitrogen (while nitrogen
is almost never used in paintball, many players call compressed air “nitro” as air is made of more than
70% nitrogen) at pressures of 3,000 or 4,500 psi.
There are two main types of HPA systems, those on which the output pressure is adjustable, and those
for which their regulator is pre-set to a fixed output pressure. HPA systems designed to screw into an
ASA are usually pre-set to deliver either 400 psi (low pressure output) or 800 psi (high pressure output.)
Never use oil or any petroleum based cleaner or lubricant in a compressed air regulator or tank. Exposure to pressurized air increases oil’s flammability and can cause a serious safety hazard. Only use
manufacturer recommended lubricants with compressed air systems, and follow the manufacturer’s
maintenance and operation instructions explicitly. If you are using your Shocker NXT with an adjustable output compressed air system, it should be adjusted to deliver about 650 psi to the Shocker NXT’s
vertical regulator. The Shocker’s regulator can accommodate a wide range of input pressures, so exact
adjustment of the air system is not critical, and either low output, or high output pre-set HPA systems
may be used as well.
While CO2 can also be used, it is less popular, since its pressure fluctuates with temperature and use.
The important thing to remember when using CO2 is that liquid CO2 must not be delivered to the Shocker NXT. If liquid CO2 were to make it past the Shocker’s regulator, it could expand into gas form inside
the paintgun, raising the pressure levels high enough to cause damage to internal seals or the solenoid
valve. Because liquid CO2 is heavier than CO2 gas, it is easily blocked through the use of gravity.

COMPRESSED AIR

FIG. 5

CO2 WITH ANTI-SIPHON

Two easy ways to properly use CO2 with the Shocker NXT are an anti-siphon tank or a remote line.
Anti-siphon tanks have a J shaped tube professionally installed inside. When the tank is screwed
into a bottom line ASA, like the one that is standard on the Shocker NXT, with their anti-siphon side
up, the tube delivers gas only. The anti-siphon tube works like a diver’s snorkel, repositioning the gas
intake from the valve to the top side of the tank.
A remote hose allows a standard (non-siphoned) CO2 tank to be carried in a player’s pack. Not only
does this make the total weight of the Shocker NXT less, but it also allows the tank to be placed vertically, so that its valve is at the top, while gravity holds the liquid CO2 at the bottom. It is important to
note, that lying down on the field, or crawling while using a remote can cause liquid CO2 to be fed to
the paintgun as the tank is turned on its side.

[CUTAWAY VIEW]

Whether using compressed air or CO2 it is important that the Shocker NXT is not exposed to sudden
“pops” of pressure. If using a standard ASA with a screw in HPA system or CO2 tank, screw the tank
in slowly, so that the valve opens slowly, and the pressure rises gently. If using an ASA with a built in
on/off valve, screw in the tank fully, then open the valve slowly. If using an HPA system or CO2 tank
with its own on/off valve, open that valve slowly. Be gentle to the internals of your Shocker NXT and
they will reward you with a long service life.

IMPORTANT
CO2 can also be used with remote hose without Anti-Siphon. [Not Shown]

G A S SYSTEM MOUNTING

PLEASE READ CAREFULLY

FIG. 6

BOTTOM OF GRIP FRAME

FIG. 7

INSTALLING SET SCREW

FIG. 8

TIGHTENING SET SCREW

The Shocker NXT offers multiple options for mounting compressed air systems or CO2 tanks. Located
on the bottom of the grip frame are a pair of industry standard 10-32 screw holes which can be used
to mount a bottom-line ASA, an S-Rail, or drop forward. Additionally, a 1/2-inch dovetail rail is machined into the bottom of the frame to allow direct mounting of dovetail accessories.
To use the dovetail rail, first use a 5/64-inch Allen wrench to remove two screws from the Shocker
NXT’s rubber grips, and open one side of the grip. Remove and unplug the 9-volt battery from inside
the grip frame. Look into the forward screw hole on the bottom of the grip. A 10-32 set screw is
included preinstalled in your Shocker NXT. If it has been removed, you may re-install it by screwing
it into the hole from the bottom of the grip frame, head first. When the set screw is in too far to keep
screwing it in by hand, use a 3/32-inch Allen wrench to screw it in further from the inside of the grip
frame. Screw the set screw in, until its bottom is flush with the dovetail rail. Slide a Max-Flo Micro, or
other accessory onto the rail, and then use your Allen wrench to lock the set screw, securing the accessory. Close up the grips and return their screws into place with the Allen wrench.
When mounting a different gas accessory or drop forward that uses dual mounting screws instead of
the rail, the set screw will need to be removed by a similar process.

PA I N T/VELOCITY/VISION

PLEASE READ CAREFULLY

FIG. 9

INCREASING VELOCITY

PAINT
Even the best quality paintballs will vary in size from one batch to the next and as weather conditions
change. While your Shocker NXT will work well even with a poor paint to barrel fit, optimal performance will be achieved with a proper fit. Paintgun barrels are available in a variety of bore sizes to
allow the user to select the best possible fit, and barrel kits like The Freak allow for easy adjustment
to paint of different diameters.
The ideal fit between the paintball and the barrel is when the ball is inserted in the bore (the end that
screws into the Shocker NXT) and does not slip or roll through to the muzzle (the business end) on its
own. The ball should sit in place, even when the barrel is pointed straight down. If the paintball can
roll out on its own, the fit is too loose. The ball should be able to be expelled from the barrel by blowing it out, like a blowgun, using a minimal amount of breath. If the ball is difficult to blow through, the
fit is too tight, which can lead to ball breakage.
VELOCITY
The velocity, or speed at which the Shocker NXT fires a paintball, must be measured and adjusted
to below the paintball field’s velocity limit immediately before each day of play (for player safety.) If
CO2 is used, velocity should be checked and adjusted multiple times during the day. Using a 3/32inch Allen wrench, loosen the velocity lock screw near the bottom of the regulator. Fire three or four
shots over a chronograph and if necessary change the velocity by adjusting the vertical regulator
with a 5/8-inch open-end wrench. Turn clockwise to increase velocity/pressure, and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the gas pressure inside the
Shocker NXT to stabilize. Adjust until the Shocker NXT is firing consistently within the limits for the
field where you are playing. For safety reasons, never adjust the Shocker NXT to fire at greater than
300 feet per second. As you adjust, check the Shocker NXT’s pressure gauge to be certain you stay
within the Shocker NXT’s operating limits of 180 to 220 psi. Once adjustment is complete, lock the
setting in place by tightening the velocity lock screw.

VELOCITY LOCK SCREW

VISION INSTRUCTIONS
When the Shocker NXT is turned on it will be
in Vision mode. The internal infra-red eye will
be used to detect whether or not a paintball
is in the breech. This feature practically eliminates the possibility of a chopped paintball.
Vision mode is indicated by a constant glow
of the light in the power button. Vision mode
can be de-activated by pressing the power
button quickly while the Shocker NXT is on.
Vision mode off is indicated by a double-tap
blinking pattern on the power button light.
Vision mode may be turned back on by once
again pressing the power button.

Example Dwell Setting: To set a dwell value of 8ms,
first press the lower programming button repeatedly
until it chirps rapidly indicating that the bottom value
of 3ms has been reached. Then, press the upper
programming button 20 times (20 x 0.25ms = 5ms.)

FIG. 11

TOP PROGRAMMING BUTTON

FIG. 12

LOWER PROGRAMMING BUTTON

The dwell and rate of fire adjustments are made using the Shocker NXT’s two programming buttons. Removing the two grip screws on the left side of the Shocker NXT’s grip frame and folding
back the grip provides access to the programming buttons. The two buttons are small, gray and
rectangular in shape. They are mounted on the front side of the circuit board facing the left edge
for easy access. Notches in the board help to identify the buttons and make them easier to press.
The upper button is located near the top of the board, just below the wiring harness plug, and the
lower button is located near the bottom of the board, just above the round black speaker.
The dwell setting determines how long the Shocker NXT holds open its solenoid valve, which ultimately affects how much gas is released to fire each shot. It is important to balance the dwell and
the operating pressure (the setting of the vertical regulator). Too high of a dwell with a low operating pressure will cause poor gas efficiency. Too low of a dwell will leave the Shocker NXT unable to
cycle through a full firing sequence. Dwell setting changes should not be used to adjust velocity.
The dwell value can be adjusted between 3 milliseconds (1ms = 0.001 seconds) and 18ms in
20.5ms increments. To adjust the dwell, make sure the Shocker NXT is already turned on and press
the upper dwell button once for every .25ms increase desired. The circuit board will chirp at each
adjustment to provide feedback that the dwell value has changed. To lower the dwell value press
the lower programming button once for every .25ms of dwell reduction. When either the lower or
upper dwell limits are reached, the circuit board will chirp rapidly in a lower tone. To set an exact
dwell value, cycle to either the upper or lower limit, and then step the dwell value the desired number of times.
To optimize your dwell setting, wear proper paintball protective goggles and gas up your Shocker
NXT with a barrel blocker in place and with no paint or hopper. Turn on the Shocker NXT and press
the power button once to de-activate Vision mode. Decrease the dwell time until the Shocker NXT
can no longer complete a full firing cycle (bolt does not close all the way) each time you pull the
trigger. Increase the dwell value one button press at a time, test firing after each change until you
hear the Shocker NXT fire a full volume shot. Increase the dwell by an additional 10 to 15 button
presses to reach the setting for best gas efficiency.

R AT E OF FIRE/REBOUND

IMPORTANT

RATE OF FIRE

The Rate of Fire adjustment determines how long the Shocker NXT will wait after activating the solenoid valve before the next shot can be fired. This time allows the bolt to return to its rear position,
gas pressure in the fire chamber to be recharged, and for a new paintball to fall into the breech.
Increasing the rate of fire setting will decrease the maximum rate of fire the Shocker NXT is capable
of achieving.
The Rate of Fire setting is adjustable from 15ms to 70ms in 1ms intervals. To change the rate of fire
setting, while the Shocker NXT is turned on, hold down the trigger and press the upper button to
increase the ROF setting and slow down how fast the Shocker NXT can shoot. Hold down the trigger and press the lower button to decrease the value and speed up how fast the Shocker NXT can
shoot. As with the dwell settings a rapid chirp indicates you have reached the limit of adjustment.

It is important to remember that the
ROF setting is not the same as a rate of
fire cap, or the maximum rate of fire the
Shocker NXT can achieve. The maximum
rate of fire or Cycles Per Second (CPS)
is calculated from a combination of the
Dwell setting and the ROF setting.

REBOUND

Cycle Time (Seconds) =
Cycle Time (milliseconds) / 1,000

The Shocker NXT features five modes of fire, ranging from traditional semiautomatic (one shot per
full trigger pull) to four levels of Rebound, an enhanced firing mode. The Rebound setting affects
the electronic switch reset sensitivity. Essentially the higher the rebound setting, the less discriminating the marker is (and therefore easier to reach and maintain higher rates of fire.)
To adjust the rebound setting degas the marker and turn it on, then open the grip panels as
though you were going to adjust the dwell. Press and hold the on/off button and immediately
press either the upper or lower programming button to adjust the Rebound setting.
NOTE: IF YOU DO NOT ENGAGE THE PROGRAMMING BUTTONS (WHILE HOLDING THE
POWER BUTTON) WITHIN TWO SECONDS, THE SHOCKER NXT WILL TURN OFF.
There are five possible rebound values, and they are adjusted similar to the dwell. Press the bottom programming button repeatedly until a rapid low chirp indicates you have reached a setting
of 1, the lowest setting. From there, pressing the up button will result in a chirp, and an increase
in the mode setting. At a setting of 1, Rebound is turned off, making the Shocker NXT legal at
paintball fields that restrict play to semi-automatic only. Progressing from settings of 2 through 5,
Rebound is activated, and becomes more sensitive, helping you achieve greater rates of fire. After
the desired Rebound setting has been reached, release the power button.

Cycle Time (milliseconds) = Dwell + ROF

The length of time needed for one complete cycle equals the Dwell time plus
the ROF time (time in milliseconds, not
number of chirps.)

To calculate the maximum CPS, the
cycle time will need to be converted
from milliseconds to seconds. This is
done by dividing it by 1,000.
CPS = 1 Second / Cycle Time (seconds)

The maximum cycle rate of a Shocker
NXT, for any given Dwell and ROF settings can be easily calculated. Divide
one second by the cycle time to arrive
at the number of shots per second.
For fields or tournaments which require
paintguns be limited to a maximum rate of
fire, you will need to make sure the Dwell
of your Shocker NXT is properly adjusted
and then calculate the proper ROF value
to create the desired CPS limit.

T R I G GER
The Shocker has four main points of trigger adjustment, providing you with the ability to set up
the perfect trigger for your style of play. Adjustments in the pre-travel, post-travel, return tension,
and switch activation are possible with a wide range of adjustment for each. It may be tempting to
set your Shocker NXT to the shortest, lightest trigger pull possible, and that is easy to do. Many
players, however opt for a slightly longer pull with enough resistance that the trigger resets more
positively, allowing them to walk the trigger to higher rates of fire. No matter what kind of trigger pull suits your fancy, it’s easy to get the Shocker NXT trigger balanced to your taste. All four
adjustment points are located in a row, on the front face of the trigger.
PRE—TRAVEL determines how far the trigger is allowed to swing forward after it is released.
The pre-travel screw is the bottom of the four adjustment screws on the trigger. To adjust your
pre-travel, use your .050” Allen wrench and turn out (counter clockwise) to allow the trigger to
reset further forward. Turn the set screw in (clockwise) to reduce pre-travel. Turning the pre-travel
screw too far in will keep the trigger from resetting after each shot. This will cause the trigger not
to activate. If you have adjusted your pre-travel and the Shocker will not fire; begin to turn the
screw out until the Shocker will fire.
POST—TRAVEL determines how far back the trigger is allowed to move. The post-travel adjustment screw is the second up from the bottom, on the face of the trigger. To adjust post-travel, use
your .050” Allen wrench and turn in (clockwise) to reduce the distance your trigger can be pulled.
Turn the screw out (counter-clockwise) to increase the distance your trigger can be pulled. Turning
the post-travel screw too far will prevent the trigger from moving far enough back to activate the
switch. This will cause the Shocker NXT to not fire. If you have adjusted your post-travel and the
Shocker will not fire; begin to turn the screw out until the Shocker will fire.
THE TRIGGER ACTIVATION POINT adjustment controls the point in the trigger pull where the
switch is activated. The trigger activation point screw is located in the third hole from the bottom on the face of the trigger. To adjust the trigger activation point, use your .050” Allen wrench
and turn in (clockwise) to make the trigger activate earlier in the trigger pull or turn the screw out
(counter-clockwise) to activate later in the trigger pull. Turning the trigger activation point screw
too far in OR too far out can and will cause the trigger not to activate.

800.922.2147

www.smartparts.com

ADJUSTMENT

Turning the trigger activation point screw
in too far may cause SEVERE TRIGGER
SWITCH DAMAGE. When you finish
adjusting the pre-travel, post-travel and
trigger activation point screws, the trigger
should stop with the solid feel of the posttravel screw making contact with the grip
frame. If the trigger activation point screw
is adjusted in too far, the trigger will feel
more “mushy” at the end of its stroke, and
the trigger switch may be damaged by
hard or rapid pulling.

Slide the trigger upward, and
forward. Move the bottom of the
trigger forward.

The bottom most trigger adjustment screw – the pre-travel adjuster – may
catch on the grip frame, preventing the trigger from being removed. If it
does, simply unscrew it counter-clockwise for a few turns with a 0.050-inch
Allen wrench, and try again.

To reinstall the trigger, simply slide it back into place, top end
first. Then move it around until the roller bearing lines up with the
trigger pivot pin hole in the frame. Reinstall the trigger pivot pin,
and use the 1/16-inch Allen wrench to secure it. Be careful not to
over-tighten the trigger pin and cause the trigger to bind.

Check the trigger’s operation, and adjust as needed
to your preferred feel.

TRIGGER RESISTANCE
Setting the trigger resistance of the Shocker NXT is achieved through the top trigger adjustment hole.
Using your 0.050-inch Allen wrench, turning the trigger resistance screw in (clockwise) puts more compression on the trigger return spring, increasing the trigger resistance. Turning the adjustment screw out
(counter-clockwise) will result in a lighter trigger pull.

D E G ASSING
At the end of each day’s use and before performing maintenance work on your Shocker NXT, it
will need to be degassed, and all paint will be removed. In an area where it is safe to shoot (the
chronograph area at a paintball field) and while wearing paintball goggles, remove the hopper
from the Shocker NXT. By turning the Shocker NXT upside down, you can empty any extra paintballs from the feedneck into your hand. Turn the Shocker NXT on, then de-activate Vision mode
by pressing the power button momentarily. Dry-fire 2 or 3 shots in a safe direction to ensure that
no paintballs remain in the Shocker NXT. Turn off the compressed air system or on/off ASA, or
unscrew the compressed air system or CO2 tank far enough to close its pin valve.

PLEASE READ CAREFULLY

Even with no CO2 or compressed air
system attached, the Shocker NXT may
still have enough gas pressure stored
in the regulator and fire chamber to fire
2 or more shots. You must degas your
Shocker NXT before performing any of
these maintenance procedures.

Continue to dry fire the Shocker NXT in a safe direction until all of the gas pressure inside has
been released. At this point the only sound you should hear when you pull the trigger is the click
of the solenoid valve. Turn off the Shocker NXT.
If using a CO2 tank or screw in HPA system, unscrew it the rest of the way.

Use a non-marring tool at least 7
inches in length to remove the fire
chamber. The handle of a wooden spoon, a piece of wooden
dowel, or even a plastic toothbrush will work well as long as it
made of a material soft enough
that it will not scratch the Shocker
NXT body or fire chamber. Insert
the dowel from the front of the
marker, angling it slightly towards
the wall of the marker body so
that it rests on the visible front
section of the fire chamber. Push
gently but firmly on the fire chamber until it emerges from the rear
of the body. Set aside the dowel
and pull the entire bolt assembly
out.

Remove the bolt guide
from the bolt assembly.
Remove the bolt sleeve
from the bolt. Set

Remove the fire chamber
front from the fire chamber,
by grasping it just behind
its front o-ring and pulling
steadily. For normal maintenance and cleaning the fire
chamber body does not need
to be removed from bolt. If
you suspect a leak in the fire
chamber’s rear inner o-ring
(the Shocker NXT will not fire
but you can hear its solenoid
click) or wish to replace this oring, remove the bolt’s forward
o-ring with an o-ring pick.

CLEANING AND REASSEMBLY

Clean the fire chamber and fire chamber
front, and inspect their o-rings for damage. Replace worn or damaged o-rings.
Pay special attention to the two internal
o-rings that seal against the bolt. Make
sure they are clean and undamaged.
Also be sure to clean the inside of the
fire chamber to prevent dirt and grease
buildup. Wiping both the external and
internal surfaces with a paper towel or
soft rag is ideal. Grease the outer and
inner o-rings liberally with SL33K. If you
removed the fire chamber from the bolt,
place them back together and reinstall
the front bolt o-ring. Thread the fire
chamber front over the front of the bolt
and snap it into the fire chamber. Set
aside.

Clean and inspect the bolt and bolt sleeve, checking
for o-ring damage. Wipe down both internally and
externally before greasing liberally and reassembling.
Slide the fire chamber forward and liberally grease the
exposed section of the bolt before sliding it back into
position. This will ensure that the rear inner o-ring on
the fire chamber is properly lubricated. Reassemble
by setting the bolt sleeve on a flat surface, flared end
facing down. Apply SL33K pneumatic grease liberally
to the external bolt o-ring and the inch or so behind it.
Apply grease to the internal bolt sleeve seal, midway
down the internal diameter of the bolt sleeve. Insert
the bolt into the bolt sleeve with the four hole bolt face
pointing up, and the flared end of the bolt sleeve facing down. Grease the four external bolt sleeve o-rings
liberally. Lay the bolt guide on a flat surface, so the
guide tip points up. Grease all three o-rings on the bolt
guide. The two small o-rings on the shaft should be
greased more liberally than the larger rear o-ring.

Install the bolt and bolt sleeve
on the bolt guide by sliding both
combined pieces over the bolt
guide. The bolt and bolt sleeve
should rest at the bottom of
the bolt guide, directly touching the end cap section. Make
sure that the flared end of the
bolt sleeve is closest to the end
cap section of the bolt guide.

Reinstall the whole assembly in the Shocker
NXT by gently, but firmly pushing it into the
body. Keep pushing in by hand until the fire
chamber stops against the front of the body.
Also make sure that the assembly goes in
smoothly and that none of the external orings are displaced or cut as they pass the
cut outs or threads in the body. Do not force
the parts to go in, as this may cut o-rings.
Instead, wiggle the parts slightly back and
forth while applying light forward pressure to
make the o-rings seat properly. At this point,
only the threads on the bolt guide should be
showing outside the Shocker body. Lightly
tap the bolt guide from the rear with the palm
of your hand, then screw bolt guide back in
with your 3/16” Allen wrench.

Remove the rubber cover from
the lower part of the vertical regulator. This will expose the vertical
safety screw slot.

Use a 5/8-inch open-end
wrench, or adjustable wrench
to turn the adjuster cap on the
bottom of the regulator, as if
you were adjusting velocity, until
the safety screw is visible in the
vertical safety screw slot. The
safety screw ensures that the
regulator will not be unscrewed
too far during normal use. Use
a 3/32-inch Allen wrench to
remove the safety screw.

Parts of the Shocker NXT’s vertical
regulator use left-handed threads.
These parts must be turned
counter-clockwise to screw them
in, and clockwise to unscrew them
– the opposite direction of normal
screws.

The adjuster cap is left-hand threaded. Turn it clockwise to unscrew it
from the vertical regulator body. Use
the open end or adjustable wrench
to completely remove the adjuster
cap.

Locate the lock screw halfway up the
side of the regulator body, and remove
it with a 3/32-inch Allen wrench. The
lock screw secures the spring platform
in place. Now that it is unlocked, use
a 9/16-inch deep well socket and
ratchet to remove the spring platform,
by unscrewing it clockwise (the spring
platform is also left-hand threaded.)
The hex faces on the spring platform
are short, so you will need to exert
a steady pressure on the socket, to
maintain contact.

The regulator spring and washer
should fall easily out of the
regulator body once the spring
platform is removed.

Clean all of the regulator parts
with a soft cloth or paper towel.
Inspect all o-rings and the
regulator seat (the clear part on
the end of the piston) for damage, and replace if necessary.
Lubricate the o-rings on the
piston assembly with SL33K.

Place the regulator spring on
the regulator piston assembly,
followed by the regulator washer.
Hold the regulator body ASA side
down, and slide these three parts
into the body. Lower the spring
platform into the regulator body
nut side up, and use the 9/16inch deep well socket to screw it
into place with a counter-clockwise motion.

The regulator piston may
require light pressure from an
Allen wrench through the top
of the regulator body. Use a
gentle hand here, as the brass
of the regulator piston can be
scratched by hard tools.

Do not lubricate the regulator seat or the o-ring on the
adjuster cap.

When the spring platform is fully seated, it will be visible through the
lock screw hole in the side of the regulator. Lock it in place by reinstalling the lock screw. Reinstall the pressure adjuster cap by screwing it
counter-clockwise into the regulator body. Turn it until the safety screw
aligns with the safety screw slot. Put a small amount of blue Loctite
242 threadlocker or equivalent (even clear fingernail polish can do in a
pinch) on the safety screw. Reinstall the safety screw.

Reinstall the rubber guard over the safety screw slot, and reinstall the regulator into the vertical ASA of the Shocker NXT. Reconnect the macroline,
and be sure to use a chronograph to re-adjust the Shocker NXT’s velocity
before use. Reinstall and lock the velocity lock screw.

Be certain that the safety screw is fully seated and the adjuster cap can
turn freely.

Service and adjustments to the regulator will cause changes in its output
pressure. Adjust the regulator to deliver between 180 and 220 psi, then
repeat the velocity adjustment procedure.

B A L L DETENT/VISION EYE

INSPECTION AND CLEANING

Use a 1/16-inch Allen wrench to
remove one of the Shocker NXT’s
ball detent covers. The wrench
should be inserted into the small
hole in the cover, where it will
engage a screw. Fully unscrew the
ball detent screw, and the entire
cover can be lifted away. The ball
detent cover screw fits into a keyhole slot in the ball detent cover, a
small foam pad should prevent it
from falling out, but keep a close
eye on it just in case.

If your Shocker NXT is equipped with a
reflective Vision eye, the LED/Sensor head
will be sitting underneath the left side
ball detent cover. If your Shocker NXT is
equipped with a break-beam Vision eye,
the LED head will be under one cover, while
the sensor head will be under the opposite
side cover. Both the Vision eye and the
pathway between it and the breech should
be clean and free from paint or debris. If
they are fouled, clean them with rubbing
alcohol and a cotton swab. Be extremely
gentle, as the Vision eye is delicate. You
do not need to remove the Vision eye to
inspect it. Vision eye removal requires
removal of the grip frame.

Inspect the ball detent
assembly. The plunger
should be round, and
smooth. It should be
able to depress into the
ball detent cover under
light finger pressure,
and spring back instantly when released.
Use a cotton swab
and rubbing alcohol to
clean the ball detent
opening in the Shocker
NXT body.

If the ball detent plunger or its spring are worn and need
replacing, this is a relatively simple task. Look at the ball
detent cover from the bottom, and press the plunger in
and out. You should see one of the plunger’s fingers moving back and forth across the detent release hole. Take
your 1/16-inch Allen wrench, and reach it into the release
hole. Use the Allen wrench to pry outward on the backside
of the ball detent plunger. Once the plunger is popped
loose, you may pull it out of the ball detent cover with your
fingers or a pair of needle-nosed pliers. You will probably
damage the ball detent spring in the process, and for this
reason it is normal to replace both the plunger and spring
at the same time. If you are careful to not put the wrench
in any further than is needed to pry against the closest
edge of the plunger, you can avoid damage to the ball
detent spring.

Carefully clean the ball detent cover with
rubbing alcohol and a cotton swab. Install the
new ball detent plunger, with its spring beneath
it, into the ball detent cover. You will need to
pinch the plunger’s fingers inward and wiggle
it until it presses inside the cover and latches
into place. Be careful, and make sure you are
doing this in a clean work area – if you slip, the
spring can jump away from you, and it is much
easier to find on a nice clean work table than in
deep shag carpet or between burger wrappers
in the back seat of a car.

PINCHING THE PLUNGER

The ball detent plunger is made of self-lubricating material.
Do not oil or grease the plunger or spring.
When reinstalling the ball detent cover to the body, make
sure that the retention screw lines up with the screw hole in
the top of the Vision eye’s flex strip. As you lower the ball
detent cover into place, be certain that the Vision eye is also
lining up properly and not being crushed. A gentle pull on
the Vision eye flex strip from the bottom of the body may be
necessary to keep the Vision eye in. Use the 1/16-inch Allen
wrench to screw in the ball detent cover screw.

Due to the internal gas filtering built into the Shocker
NXT, removal and or disassembly of the solenoid
valve is not required during regular maintenance and
may actually shorten its service life. Leave it where it
is and lead a happy life.

G R I P FRAME REMOVAL
01

Degas the Shocker NXT. Disconnect the macroline running from
the ASA or compressed air
regulator to the Shocker NXT’s
vertical regulator.

Remove the four screws that hold
the rubber grip on the grip frame,
and remove the rubber grip.

03
It is not necessary to remove
the 9-volt battery from the
grip frame, but you may find
it easier to complete the next
step if you first remove the 9volt battery and unplug it from
the battery clip.

WIRING HARNESS

FIG. 23

The wiring harness carries
electrical signals between the
Shocker NXT’s lower (grip frame)
circuit board and the Vision
circuit board which is mounted
on the solenoid valve. Remove
the wiring harness by getting as
close to the lower circuit board
as possible and gently removing
the wiring harness plug in a
careful side to side motion until
the harness plug comes free.

PORT INSERTS

Using the 5/32” Allen wrench, unscrew and remove the two grip
frame screws.
CAREFULLY separate the grip frame from the body, paying careful
attention to the wiring harness attached to the circuit board at the
midway point of the grip frame. Pull wiring through grip frame gently
and set aside grip frame assembly.

Use caution while handling the Shocker NXT Body. Excess strain on
the solenoid valve can damage the fine threads of its mount screws.
The Solenoid valve should not be removed during normal maintenance.

INSTALLATION OF PORT INSERTS
Located below the Bolt Guide on the rear of the Shocker NXT are the threaded ends of two port inserts.
The Port Inserts are slender rods equipped with very fine o-rings. They serve to divide gas passages
inside the Shocker NXT. Correct installation of the Port Inserts requires the use of specialized pneumatic
alignment equipment at the Smart Parts factory. Improper installation can damage the Port Insert seals
and misalignment will prevent the Shocker NXT from functioning. The Port Inserts and their o-rings are
non-wear items and do not ever need to be removed for the Shocker NXT for anything short of body milling or anodizing. Even if someone offers you free beer and pizza, do not remove the Port Inserts.

V I S I O N EYE RE MOVAL
01
The Vision eyes are what the
Shocker NXT’s circuits use to
determine if a paintball has been
loaded into the breech.
To remove or install a Vision eye,
remove the grip frame from the
body. Reflective Vision eyes are
located under the right side ball
detent cover, and beam-break
eyes are positioned under both
ball detent covers. Remove the
appropriate cover(s) for your type
of eye.

REMOVAL AND INSTALLATION

Reflective Vision eyes are on a single flex-strip, and break-beam eyes
have a Y-shaped strip. Unplug the bottom end of the strip from the solenoid (upper) circuit board. Remove a reflective Vision eye by grasping
its eye end and gently wiggling the flex strip up and out of the body. Remove a break-beam Vision eye by first lifting each eye out of its recess
in the body. The 1/16 inch Allen Wrench may be helpful in this task.
Then gently pull the bottom end of the flex strip and carefully guide the
two eye ends into the body and out the bottom one at a time. Inspect
the Vision eye flex strip for damage. The eyes must be removed one
at a time, as they may be damaged by trying to pass them through the
opening together. Damage to the infra-red LED and detector, scratches
across its circuit traces, or cracks or sharp bends in the flex strip can all
cause Vision failure, and are signs to replace the flex strip.

To install a reflective Vision eye,
thread its tail into the Vision slot
next to the right side ball detent
opening. Guide the flex strip out the
bottom of the body. For a breakbeam Vision eye, install from the
Vision opening in the bottom of the
receiver. One at a time, carefully
guide the eyes up to the ball detent
openings. This will require some
gentle wiggling of the flex strip to
achieve. Here again, your 1/16 inch
Allen Wrench may be helpful in
guiding the eyes to their appropriate channels.

04
Plug the bottom end of the flex strip into the solenoid circuit board.
The metal contacts on the flex strip should be facing away from the
Shocker NXT body.

SELECTING VISION MODES

IMPORTANT

The Shocker NXT circuit board features 3 Vision modes: Break-Beam Vision, Toggle Vision and Reflective Vision.

The type of Vision the Shocker NXT will use is
selected by holding down the mode buttons and
turning the Shocker NXT on. With the Shocker NXT
unloaded and degassed, open the grip and hold
down the top programming button, then turn the
Shocker on to select Break–Beam Vision. Use the
lower button to select Toggle Vision, or both buttons at the same time to select Reflective Vision.

Break-Beam Vision is the standard Vision mode for the Shocker NXT, and works with Shocker Break–Beam Vision
eyes. In Vision mode the Shocker NXT will not fire unless a paintball is in the breech, breaking the beam between
the infrared emitter and detector.
If the ball detent plungers become excessively worn, or improperly fitting aftermarket ball detents, or an aftermarket body is used, it is possible for the Shocker NXT to be loaded, and for the paintball to roll forward of the Vision
beam. In this case, Vision can still be used by switching to Toggle Vision Mode. In Toggle Vision mode the Shocker
NXT will fire after the break beam has detected a paintball, even if the ball has rolled forward and the beam is no
longer broken. Toggle Vision mode will automatically bypass the Vision eyes if they become blocked by debris,
defaulting to limited rate of fire.
Reflective Vision Mode allows the Shocker NXT to be backwards compatible with older Shocker SFT custom
bodies, which only have room for a Reflective Vision eye. Reflective Vision should only be used when a Reflective
Vision eye is installed.

REASSEMBLY

To reconnect the grip frame, bring the body and grip frame close
together, very gently inserting the wiring harness directly through
the opening in the top of the grip frame, just above the battery.
Now bring the grip frame and body all the way together, taking extra care not to allow any of the black wires to get wedged between
the clear on/off button of the grip frame and the on/off switch located on the back end of the upper circuit board (the on/off button
is small and gray, like the programming buttons.)

Look carefully at the wiring
harness. There is a raised line
on the side of the wiring harness plug that prevents it from
being plugged in backwards.
This line should be closest to
the battery, on the side of the
connector away from the circuit board. Push the harness
plug in firmly until it stops.
Use a thumbnail to make sure
the plug is fully seated by
pushing on its edges.

Thread in the two grip frame
screws and tighten them with
the 5/32-inch Allen wrench. Now
reconnect the wiring harness to
the lower board.

Getting the wires caught
between the on/off switch

IMPORTANT

BREAKING PAINT.
— Paint to barrel match is wrong. The paint you are using is too large for the barrel you are
shooting it through. Get a Freak System and select the proper size insert, or find a paintball that
fits your barrel properly.
— Ball Detents are damaged or missing. Check to make sure ball detent plungers are intact and
reactive on both sides. Replace if damaged or missing.
— Paint is too low quality or too brittle. Switch to a name brand, high quality manufacturer.
— Turn on Vision eye (if so equipped).
— Check Shocker battery. It may be low, causing incomplete cycling.
— Loader may not be keeping up. Check loader batteries or use a faster loader.
AIR LEAKS DOWN THE BARREL WHEN GASSING UP THE SHOCKER.
— The o-rings on the internal surface of the fire chamber are worn. Clean and inspect the bolt assem–
bly and lubricate thoroughly.
WHEN GASSED UP, LITTLE OR NO AIR SEEMS TO BE GETTING TO THE SHOCKER.
— Degas, then remove the internals. Check for o-ring binding, grease with SL33K, then reinstall.
— Bolt may be jammed, check for paint shell or debris.
AIR IS LEAKING INSIDE THE SHOCKER.
— Manifold mounting screws are loose. Tighten screws to stop the leak but DO NOT OVERTIGHTEN.
— Solenoid screws are loose. Tighten screws to stop the leak but DO NOT OVERTIGHTEN.
— Solenoid may require servicing. Contact Smart Parts.
THE SHOCKER IS GASSED UP, BUT WILL NOT SHOOT.
— Turn the Shocker NXT on.
— Battery may be dead. Replace with fresh name brand alkaline 9-volt battery.
— Check to see if solenoid wiring harness has come free from either end of the circuit board.
Reconnect, if necessary.
— Vision eye is on but no paint is loaded. Add paintballs or turn Vision off.

Reset the dwell for optimum efficiency, see the Dwell Section for more details.
Change to a fresh name brand 9-volt alkaline battery.

THE SHOCKER HAS LOW VELOCITY OR WON’T FIRE.
— Your battery is low. Replace with fresh name brand 9-volt alkaline battery.
— Turn the on/off valve on all the way.
— Check your operating pressure so that it’s between 190-220psi. Increase pressure up to 220psi,
if necessary.
— The Dwell setting may be too low, causing the bolt to return before enough gas has been re–
leased to get the paintball up to speed. Try increasing the Dwell setting, especially if the pres–
sure is already as high as 190 psi.
— Clean and inspect regulator.
— Clean, inspect and lubricate the Shocker NXT’s internals.
— Check paint to barrel match. Paint may be too large or too small for the barrel you are shooting
it through. Consider a Freak Barrel System or find a paintball that fits your barrel properly.
— Replace the rear firing chamber o-ring.

THE SHOCKER HAS FIRST SHOT DROP OFF (FSDO)
—

—

If the Shocker NXT fires at low velocity or will not fire on the first trigger pull after sitting still for

a few minutes, but fires at proper velocity on all subsequent shots, this first shot drop off may be
caused by dirt or under lubrication. Degas, disassemble, clean and inspect the bolt assembly.

Liberally lubricate the bolt assembly with SL33K Shocker Lubricant upon reassembly.
If First Shot Drop Off continues after cleaning and lubrication, increase the dwell setting. See the
Dwell Section for more details on Dwell adjustment.

—

TECH SUPPORT

At some paintball fields or tournaments you may face rules that limit how fast a marker may fire.
To slow down how fast the Shocker NXT can fire, you will need to rein it in by raising the ROF
setting, which makes it wait longer after each shot. With the Shocker NXT degassed, unloaded
and guarded with a barrel blocker, open the grip, turn on the Shocker and press the lower adjust–
ment button while holding down the trigger. See the Rate of Fire/Rebound Section for details on
ROF adjustment and calculating maximum cycle rates.

Smart Parts warrants for one (1) year to initial retail
purchaser that the paintball marker and regulator are free
from defects in materials and workmanship. Disposable
parts (batteries, o-rings, seals, etc.) are not warranted.
The valve assembly is warranted for six (6) months. The
solenoid and electronics on the marker are warranted for
six (6) months, plus an additional warranty of six months
for electronic parts only (installation and labor are not
included.) This warranty does not cover surface damages
(scratches and nicks), misuse, improper disassembly
and re-assembly, attempts made to drill holes or remove
metal from the external surfaces which could degrade
performance and reduce pressure safety factors of the
marker. Do not make changes to the basic marker parts
without written approval. The only authorized lubricant for
the marker is SL33K Lubricant. Use of any other lubricant
could result in voiding your warranty. Paintball markers are non-refundable. This warranty is limited to repair
or replacement of defective parts with the customer to
pay shipping costs. This warranty is effective only if the
customer returns the warranty registration card enclosed
with the marker. The warranty is non-transferrable. Do not
attempt to alter the trigger assembly in any way, as this
will void your Smart Parts Inc. warranty. Trigger alteration
of any kind may result in serious injury.
