MAINTENANCE
The eXTCyTM has been designed with
simplicity in mind so that you can
concentrate on your game instead of your
marker. It has only one major moving part in
its valve system, with a minimal number of
seals. This DOES NOT mean that you should
neglect your eXTCyTM. If you take care of
it off the eld, your eXTCyTM will take care
of you on the eld. For best performance,
clean and grease your eXTCyTM frequently.
Many players disassemble and clean their
eXTCyTM after every day of use. While this
may seem a bit extreme, being vigilant in the
upkeep of your eXTCyTM will extend its useful
life considerably, and catch any problems
when there is time to correct them before
the next game. Playing in the rain will not
damage your eXTCyTM. In fact, the eXTCyTM.
has been tested and proven to function
underwater. However, long-term exposure
to moisture can cause rust damage to
some of the eXTCyTM’s screws, so if your
eXTCyTM should become waterlogged,
remove the barrel, stock, eye covers 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. Lubricate the
eXTCyTM ONLY with GR33SETM pneumatic
grease. Use fresh, high quality paintballs for
best performance.

BARREL BLOCKER/HOPPER
PLEASE READ CAREFULLY
BARREL BLOCKER
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 eXTCyTM 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 eld 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 eXTCyTM 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 eXTCyTM is on a “live” paintball eld and all
persons involved are wearing proper paintball protection.
HOPPER
The eXTCyTM is a high performance tournament grade paintball marker. Its low-force bolt and VisionTM
anti-chop system will prevent paintballs from being chopped if the hopper is not able to load paintballs
as fast as the eXTCyTM is being red. If you want to realize the eXTCyTM’s maximum repower 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 eXTCyTM.
The eXTCyTM is equipped with a clamping feedneck that allows it to adapt to the small size differences
in hopper neck sizes, yet lock or release quickly. Using a 7/64-inch allen wrench, loosen the clamping
feedneck before installing a hopper.

GASES
NEVER PUT OIL IN A COMPRESSED AIR REGULATOR OR
TANK - ONLY APPLY MANUFACTURER RECOMMENDED
LUBRICANTS.
COMPRESSED AIR
TM
The eXTCy
is a low-pressure paintgun. It operates at approximately 160 psi, which means it is capable of
functioning well with either high-pressure 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 eXTCyTM.
Whether using compressed air or CO2 it is important that the eXTCyTM is not exposed to sudden “pops”
of pressure. Always turn-on or screw-in a compressed air system or CO2 slowly, so that the valve opens
slowly and the gas pressure inside the marker is raised smoothly. Be gentle to the internals of your
eXTCyTM and they will reward you with a long service life.
High Pressure Air systems (HPA) are the preferred power source used in paintball and with the eXTCy
TM
because they are unaffected by temperature uctuations 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
at pressures of 3,000 or 4,500 psi. Although pure nitrogen is almost never used in paintball, many players
call compressed air “nitro” as air is made up of more than 70% nitrogen, allowing the two gasses to be
used interchangeably in paintball equipment.
The eXTCy
TM
is congured for use with screw-in style HPA systems. Although HPA systems pre-set to
deliver approximatly 400 psi (low output) will work with the eXTCyTM, 800 psi (high output) systems are
preferred, to reduce the risk of gas starvation under rapid re.
Never use oil or any petroleum based cleaner or lubricant in a compressed air regulator or tank. Exposure to
pressurized air increases oil’s ammability 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 eXTCyTM with an adjustable output compressed air system, it should be set to deliver
about 800 psi. The eXTCyTM’s vertical regulator can accommodate a wide range of input pressures, so
exact adjustment of the air system is not critical.
NOTICE
Due to shipping restrictions, CO2 and HPA tanks are sold empty. They must be lled before they can be
used. Most paintball shops and elds are equipped to ll HPA tanks. Paintball shops, elds, many hardware
stores and sporting goods stores will have the equipment and trained personnel to ll paintball CO2 tanks.
FIG. 3
HPA TANK BEING FILLED
NOTICE
TM
The eXTCy
is factory congured for use with
CO2. Its dwell setting must be changed to obtain
optimum performance with HPA. See the Firing
Modes / Dwell section of this manual to learn how.
NOTICE
Although the eXTCyTM can be powered by
compressed air, typical home, garage or industrial
air compressors cannot provide the high pressures
required to ll a paintball HPA tank. Paintball HPA
systems can be relled by paintball elds and
stores which use higher pressure compressors
similar to those used in the SCUBA and reghting
industries.

PLEASE READ CAREFULLY
USING CO
CO2 is usually not recommended for electronic paintball markers. This is not the case, however with
the eXTCyTM. The eXTCyTM can function extremely well with CO2 as a power source, but doing so does
require the correct conguration. The use of CO2 will not damage the seals in the eXTCyTM, freeze or
cause damage to its circuit board.
The important thing to remember if using CO2 is that best performance can be achieved when only
gasseous CO2 is fed to the eXTCyTM, and liquid CO2 remains in the tank.
Although the relief valve integrated into the eXTCyTM’s vertical regulator provides the marker with
protection from pressure spikes, those pressure uctuations can cause poor performance, and
temporary blockage of the eXTCyTM’s solenoid valve.
The bottom-line ASA tting on the eXTCyTM places the CO2 level, like in Figure 5. When the marker is
held in typical ring positions the liquid CO2 will pass through the valve into the marker unless an anti-
siphon system is used.
Anti-siphon CO2 tanks contain a J-shaped tube that draws gaseous CO2 from the top of the tank
when it is in a horizontal position. Anti-siphon tubes must be professionally installed, to ensure that
critical safety checks are performed during valve installation. Anti-siphon CO2 tanks should not be
used with remote hoses.
Alternative CO2 arrangements include placing the CO2 tank vertically in a pack, and using a paintball
remote hose to feed CO2 to the eXTCyTM. This arrangement not only prevents liquid CO2 from entering
the marker, but also makes the marker assembly lighter weight. Another possible conguration is to
use a third-party ASA or ASA mounting adapter which mounts a standard CO2 tank at an angle like in
Figure 4. In this arrangement gravity keeps the liquid CO2 below the valve neck.

The bottom-line ASA tting on the eXTCyTM can be removed by unscrewing the two industry-standard
10-32 mount screws holding it to the grip frame after unscrewing and removing its on/off knob. If
replacing the ASA, be sure the model chosen takes into account the type of gas system being used
(horizontal for anti-siphon CO2 tanks or compressed air, angled for standard CO2 tanks).

WHEN STORING FOR FOR

TM
The eXTCy
consistently deliver the amperage needed to operate the eXTCy
is powered by a standard 9-volt alkaline battery. Lower cost “heavy duty” batteries will not
TM
reliably. Erratic performance, especially
drops in velocity or skipped shots during rapid re can result from a battery that is not delivering full
power.
The eXTCyTM is also compatible with 9-volt rechargeable batteries. Because specications of batteries
vary widely from brand to brand, use of any rechargeable battery will require testing to determine if it
can power the eXTCyTM reliably and t correctly in the grip frame. Some NiCD “9v” rechargable batteries
actually operate at 7.2 volts. These types of batteries will not work well with the eXTCyTM.
Each time the eXTCyTM is turned on, the power button LED will blink 5 times rapidly, with its color indicating
the estimated charge level of the battery. Green indicates a charge level between 75% and 100%. Yellow
denotes a charge level between 50% and 75%, while red ashing indicates that the remaining charge is
estimated to be below 50%. It is important to note that different types and even brands of rechargeable
batteries will give different readings than alkaline batteries., so experience will be the best teacher as to
how much remaining use to expect once a reduced charge level is indicated.
Any time the eXTCyTM exhibits erratic performance, drops velocity or skips shots while rapid ring, does
not shoot or does not turn on, the rst step in troubleshooting should always be to replace the battery with
a brand-new, name-brand alkaline battery.
To replace the eXTCyTM battery, use a 5/64-inch allen wrench to remove the two screws from the left side
of the rubber grip, then open the grip. Be careful opening the grip from the grip frame. Folding the grip
back around the trigger frame may seem convenient, but may cause tearing or stretching in the center of
the grip, which will cause it to pucker or t poorly when reinstalled. As an alternative to folding the grip
open, simply remove it entirely by removing the two grip screws from its right side.
FIG. 6
ALKALINE BATTERY
Remove the old battery, taking care not to bend, kink or strain its wires. Unsnap the battery from its
connector by pulling on the connector, not the wires. Snap in a fresh battery, then place that in the grip
frame, tucking the wires into place, before closing and re-securing the grip. The battery and connector
should t snugly in the battery space, so that they do not shift around during use. Some off-brand batteries
may be too large to t correctly in the grip frame. If this is the case, do not force the battery into position,
instead replace it with a name-brand alkaline battery.

VISION OPERATION
VISION BYPASS
The eXTCyTM is equipped with a VisionTM break-beam anti-chop system, allowing it to acheive the
highest possible rates of re without chopping or mis-feeding paintballs.
The eXTCyTM circuit board is linked to a light emitting diode and detector installed in the marker’s
breech. When a paintball drops down the feedneck into the breech, it breaks the light beam and
the eXTCyTM circuit board detects its presence. When the VisionTM system is activated, the eXTCyTM
will not re until it “sees” a paintball in the breech. This prevents the marker from dry ring or from
chopping a paintball in half by ring before the ball is completely loaded.
There may be times when it is desirable to bypass the VisionTM system, such as dry-ring the eXTCyTM
to test electronic adjustments, or when de-gassing.
While the eXTCyTM is turned on, pressing and holding the power button for approximately one-half
second will turn the VisionTM system off, allowing the marker to re whenever the trigger is pulled,
whether or not there is a paintball in the breech. Pressing for approximately a half second will also turn
VisionTM back on.
When VisionTM is on, the power button will glow green. When it is off, the button will glow red.

FSDO Compensation: (Power Button LED blinks slowly red and green) - When a marker rests, its bolt
may stick in position and cause a low-velocity shot the next time it is red. This is known as First Shot
Drop-Off, or FSDO. FSDO Compensation increases the dwell time of the rst shot of a group, providing
additional time to break friction between the breech and the bolt’s o-rings before the bolt moves
forward. FSDO Compensation may be adjusted from zero (off) to 15 milliseconds in 1 millisecond
increments. When the marker rests for 20 seconds or more, the next shot red will have the FSDO

TRIGGER ADJUSTMENT
IMPORTANT
THE TRIGGER MUST COME TO A STOP WITH ITS
ADJUSTMENT SCREW AGAINST THE GRIP FRAME OR
DAMAGE TO THE CIRCUIT BOARD AND OR TRIGGER
SWITCH MAY OCCUR.
The length of the eXTCyTM trigger pull is fully adjustable.
A setscrew in the lower half of the trigger sets the post-travel adjustment, or how far back the trigger
can be pulled. Turning the screw clockwise with a 0.05-inch allen wrench will shorten the trigger
pull. Turning counter-clockwise will increase it. When setting post-travel limit, it is important that the
trigger pull is not set so short that the trigger does not activate the microswitch on the eXTCyTM’s
circuit board, as this would leave the marker unable to re. Similarly, the post-travel adjustment screw
must butt up against the trigger frame when the trigger is pulled. If the post-travel screw is underadjusted the trigger will stop against the microswitch inside the marker, instead of on the screw. This
situation can cause damage to the microswitch and or circuit board when the trigger is pulled hard.
The forward limit of the trigger’s movement, or pre-travel is adjusted by the use of a 1/8-inch allen
wrench. The pre-travel trigger adjustment screw is located at the bottom of the trigger guard where it
meets the grip frame. It may be helpful to remove the marker’s rubber grips to provide easier access
when making adjustments. As when changing the battery, it is better to completely remove the rubber
grip than to only open one side and fold it past the trigger guard. Turning the pre-travel adjustment
screw clockwise decreases how far forward the trigger can move, while turning counterclockwise
increases. If the trigger is not adjusted to swing far enough forward when released, the microswitch
inside the eXTCyTM will not be able to reset, resulting in the marker not ring.
Always check the trigger after making adjustments. Be sure that the trigger switch clicks when the
trigger is pulled, and again when it is released. Also make sure that when the trigger is pulled it is
being stopped by the post-travel adjustment screw, not by pressing up against the microswitch
inside the marker.

UNLOADING/DE-GASSING
PLEASE READ CAREFULLY
At the end of each day’s use and before performing maintenance work on your eXTCyTM, it will
need to be de-gassed, and all paintballs must be removed.
In an area where it is safe to shoot (such as the chronograph area at a paintball eld) and while
wearing paintball goggles, remove the hopper from the eXTCyTM. By turning the eXTCyTM upside
down, you can empty any extra paintballs from the feedneck into your hand. Turn the eXTCyTM on.
Dry-re 2 or 3 shots in a safe direction to ensure that no paintballs remain in the eXTCyTM. In order
to dry-re the marker, the VisionTM anti-chop system must be turned off (see VisionTM operation) or
set to one of its delayed modes (see Electronic Adjustment).
Turn off the HPA system if it is equipped with its own on/off control, or turn off the HPA system or
CO2 tank by turning the bottom-line ASA control knob counter-clockwise. Dry re the eXTCyTM 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. Often this sound will
be too quiet to hear. Turn off the eXTCyTM.
If using a CO2 tank or screw in HPA system, unscrew it from the bottom-line ASA.
EVEN WITH NO CO2 OR COMPRESSED

FIELD STRIPPING
The valve system in the eXTCyTM has only one major moving part. Regular cleaning and lubrication is necessary to ensure accurate and consistent performance. The eXTCyTM
should be eld stripped, cleaned and lubricated any time it shows erratic performance, becomes contaminated with paint, dirt or other debris, or for general maintenance after
3 or 4 days of use.
Unload and de-gas the eXTCyTM. Remove the barrel and use a 5/16-inch allen wrench to unscrew and remove the bolt sleeve from the back.
Using a soft, non-marring tool like a wooden chopstick or plastic toothbrush, push the bolt and bolt stop out the back of the eXTCyTM. Clean the interior of the receiver, the bolt
sleeve, bolt and bolt stop with a clean cloth or paper towel. Inspect their o-rings for signs of damage such as cuts or rips, and replace if necessary. Lightly lubricate all o-rings
with GR33SETM paintgun grease. Use GR33SETM sparingly, as over-lubrication can cause the eXTCyTM to operate inconsistently. Do not lubricate the rearmost o-ring on the bolt
sleeve, it provides friction to keep the bolt sleeve in place during operation.
Slide the bolt stop onto the bolt from the rear. Slide the rear of the bolt into the bolt sleeve. Hold this entire assembly vertically with the front of the bolt pointing upward, and
insert it up into the back of the eXTCyTM. Screw the bolt sleeve into the back of the eXTCyTM by hand, taking care not to cross-thread it into the receiver.
Use the long end of a 5/16-inch allen wrench to turn the bolt sleeve until it is snug. Take care not to over-tighten the bolt sleeve, it only needs to t snugly in place.

VISION/DETENT CLEANING
The VisionTM eye covers of the eXTCyTM are easily removed to provide access to both the VisionTM sensors and the marker’s ball-detents. To remove the eye covers, rst unload
and de-gas the marker following the instructions in this manual, then use a 0.050-inch allen wrench through the eye-cover access hole to unscrew the eye cover retaining screw,
then tilt the eXTCyTM to the side, and if necessary tap it lightly against one hand to work the eye cover out.
With the eye cover removed, an o-ring pick can be used to pry the VisionTM LED or detector out of its pocket by one of its top corners. Care must be taken not to scratch the
dome shaped lens molded into the body of the eye. With the eye gently folded out of the way, the eye, eye pocket and ball detent opening in the breech may all be thoroughly
cleaned with a cotton swab.
If the ball detent is worn to the point that it does not protrude slightly into the breech, or dirty to the point that it does not spring easily in or out, it may be removed from the eye
cover for cleaning or replacement. To remove the ball detent, use an o-ring pick to carefully pry back the ball detent retaining ngers one at a time and work the detent out of the
eye cover. If the ball detent is excessively worn, it must be replaced for proper operation of the eXTCyTM. The ball detent spring may become bent or damaged during removal
of the ball detent. If this happens, it must be replaced. After cleaning or replacement, t the ball detent spring into the ball detent, set its other end on the spring guide in the eye
cover, then carefully work the detent past the detent retaining ngers. Note the alignment of the ball detent for a proper t, its wider at edges should be at the top and bottom.
When re-installing the eye cover, use the long end of the allen wrench to tighten the eye cover retaining screw. Take care not to cross-thread the eye cover retaining screw, or
tighten it beyond a snug t, these can cause permanent, non-repairable damage to the breech.

The internal gas lines and electronic components of the eXTCyTM are well protected inside its body – however they are delicate and may be damaged by improper handling
or re-installation. For this reason it is highly recommended that full disassembly of the eXTCy
only when necessary to x a problem or install an upgrade. Removal of internal hoses from their barbed ttings will stretch them to the point that they cannot be re-used
without causing leaks. In other words, if it ain’t broke, don’t x it.
Occasionally a more thorough disassembly of the eXTCy

Using a 1/8-inch allen wrench, remove the breech screw from the front of the breech. Next remove the two grip frame screws securing the grip frame to the body. Carefully
slightly separate the grip frame from the receiver. Be aware that the clear power button can fall out of its position in the side of the grip frame. Be careful not to drop or lose
it. The body will still be connected to the grip frame by the hose running between the front of the grip frame and the solenoid valve on the circuit board.
Tilt the body slightly away from the grip frame and carefully use a 1/8-inch allen wrench to unscrew the barbed banjo tting which connects the gas supply hose to the grip
frame. Alternatively, the hose may be pulled off of the barb in the grip frame - doing so will require the hose to be replaced however, as its end will have been stretched by
the barbed tting and will no longer seal reliably.
Completely separate the body from the grip frame. Watch to make sure the battery clip does not snag in the grip frame as the two parts are separated.
Reassembly of the grip frame to the body is done in the reverse order, taking care not to allow the battery wires to or hoses to become pinched or entrapped while joining
the body to the grip frame. Use the long end of the allen wrench when reinstalling the banjo ttings and grip frame screws, to avoid over-tightneing.
Over-tightening or cross threading screws or ttings may result in permanent, nonrepairable damage to the breech.

The circuit board is removed from the body by rst unplugging the VisionTM wiring harness from its socket. Take care to grasp the plug and remove it - do not pull by the
wires or they plug may be damaged.
Using a 1/8-inch allen wrench, unscrew the 2 banjo ttings which attach the circuit board to the body and breech.
The circuit board may then be carefully lifted away from the body and breech.
When re-attaching the circuit board to the body and breech, take extreme care not to cross thread the ttings. Use the long end of the allen wrench to tighten the gas ttings
and all screws, being careful to tighten them snug without over tightening. Over-tightening or cross threading screws or ttings may result in permanent, nonrepairable
damage to the breech.
Be sure to guide the battery clip down into the grip frame before re-joining the grip frame and receiver. Make sure the clear power button does not fall out of its place during
reassembly.
Be certain all wires and hoses are tucked into their places before rejoining the grip frame to the receiver. If the grip frame does not t snugly to the receiver do not force it.
Instead, pull the grip frame back away and look for hoses, wire, or improperly placed parts blocking the t.

VERTICAL REGULATOR
SERVICE AND ADJUSTMENT TO THE REGULATOR WILL
CAUSE CHANGES IN VELOCITY. ALWAYS RE-CHRONOGRAPH
THE MARKER FOLLOWING THE PROCEDURE IN THIS MANUAL
AFTER WORKING WITH THE REGULATOR.
REGULATOR SERVICE
Although explained here, regulator service should only be performed by a GOG PaintballTM trained airsmith.
With the marker unloaded and de-gassed, unscrew the regulator from the marker and remove the grip
frame following the instructions in this manual. Take care not to lose the lter screen that sits inside the
vertical regulator’s ASA connection.
Using a pair of snap-ring pliers, remove the snap-ring from the bottom of the regulator and slide the
regulator off the swivel. This is the preferred way to separate the regulator from the hose and bottomline
ASA because it does not disturb the sealed hose ttings and is not likely to cause a leak.
Using a 7/16 open end or adjustable wrench, engange the wrench ats in the sides of the spring platform
and remove it from the bottom of the regulator body. The regulator spring will now be free to fall out into
your hand. The brass regulator piston may be removed by tapping the regulator body against a table top
or solid, but soft surface such as a block of wood.
At this level of disassembly, the seal in the end of the piston and the regulator body may be inspected,
cleaned with a soft cloth or cotton swab, and replaced if necessary. If the regulator seal shows signs of
damage, it may be removed and ipped over so that its back side is used instead. If both sides of the seal
are damaged, it must be replaced. Lightly lubricate all o-rings with GR33SETM for reassembly.
Do not lubricate the regulator seal at the end of the piston.

REGULATOR SERVICE, CONTINUED
The relief valve assembly should only be removed if it is constantly leaking. Occasional venting, especially
if using CO2, is normal and does not indicate a malfunction. The relief valve assembly may be removed
with a 5/32-inch allen wrench.
The velocity adjuster is located inside the lower end of the spring platform and similarly should only be
removed if shown to be the source of a leak or clog. First the internal c-clip ring must be removed from
inside the spring platform. This must be done with a pair of narrow snap-ring pliers. Some airsmiths have
used bench grinders to re-shape standard snap-ring pliers for this task. The adjuster is equipped with
left-hand threads and will need to be turned clockwise for removal. If regulator blockage is suspected, be
sure to inspect, and if necessary replace the inlet lter in the side of the velocity adjuster.
The vertical regulator is reassembled in the reverse order of disassembly. The piston slides into the
regulator body wide end rst, followed by the regulator spring. The spring platform should be tightened
for a snug t. Do not over-tighten. Re-attach the regulator swivel to the bottom end of the regulator and
secure it in place with its snap-ring. Reinstall the assembled regulator into the marker. Re-adjust velocity
after servicing the regulator.

TROUBLESHOOTING
MARKER EXHIBITS FIRST SHOT DROP-OFF (FSDO)
• FSDO is a low velocity, or non-ring rst shot, followed by normal shooting and is often
caused by debris in the bolt or a poorly lubricated bolt. Clean the bolt, breech, bolt stop
and bolt sleeve, and lubricate them with GR33SE
section of this manual.
• FSDO can be caused by dwell and or FSDO Compensation settings that are too low
for the marker’s gas supply and conguration. Follow the directions in the Electronic
Adjustment section of this manual and set the dwell to the minimum recommended setting
for the marker’s gas supply and conguration or higher, and the FSDO Compensation
setting to the default value or higher.
MARKER EXHIBITS INCONSISTENT VELOCITY OR DROPS OFF SIGNIFICANTLY
DURING RAPID FIRING
• Check paint quality. Your marker is optimized for use with fresh, high-quality paintballs.
Paintballs of inconsistent quality, or paintballs that have been exposed to humidity or
temperature extremes may vary in size or roundness causing inconsistent operation.
• Gas pressure could be low. Fill gas source and make sure gas supply is turned on.
• Battery may be low. This will be most noticeable with velocity dropping and then entire
shots not ring during rapid re. Replace battery with a new name brand alkaline battery.
• Regulator may be contaminated or damaged. Follow the instructions in this manual or
