Unpack the G-1TM and its stock. Using the included 1/8-inch allen
wrench, attach the stock to the rear of the G-1 with the two included
screws.
Install the included barrel
into the G-1TM, screwing it
into place hand tight. Put the
supplied barrel blocker over
the end of the barrel, securing
its cord as far back on the
G-1TM body as possible, and
cinching it tight.
Fill the loader with paintballs. If it is a powered loader, turn it on. While wearing ASTM compliant paintball goggles, in an area where all bystanders are protected, remove the barrel
blocker and re over a chronograph to measure the velocity. Using a 5/32-inch allen wrench on the adjuster in the bottom of the vertical regulator, turn clockwise to increase the
velocity/pressure, and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the gas pressure inside the G-1TM to stabilize. Adjust until the marker
is ring consistently within the limits for the eld where you are playing (for safety reasons, never adjust the G-1TM to re at greater than 300 feet per second). Depending on what
modes of re are allowed at the eld where you are playing (semi-automatic, rebound, etc.) you may need to adjust the G-1TM’s ring mode. See the Electronic Adjustment section
for more information.
Fit a paintball loader into the feedbeck
of the G-1TM. Use a 7/64-inch allen
wrench to lock the loader in place.
Powered force-feed loaders are
recommended, as the G-1 has little
recoil, and can easily outpace an
unpowered or agitating loader.
Gently gas up the G-1TM by
slowly turning on the air system
or screwing the CO2or screw-
in style HPA system into the
bottom-line ASA.
A gentle rise in pressure is
important, as a sudden blast
may reduce the service life of
the G-1®’s internal components.
Turn on the G-1TM by
pressing the power button
momentarily.
Although the power button
serves as the G-1TM’s safety
switch to prevent accidental
ring, it should never be relied
upon in place of a barrel blocker
and proper eye protection.

Have your compressed air
(HPA) or CO2 tank lled by
a person who is properly
trained to do so. If using an
HPA system with an on/off
valve, make sure it is in the
OFF position. If using a CO2
tank or screw-in style preset
HPA system, ll it while it is
removed from the marker.

The G-1TM 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 G-1TM. If
you take care of it off the eld, your G-1TM
will take care of you on the eld. For best
performance, clean and grease your G-1TM
frequently. Many players disassemble and
clean their G-1TM after every day of use.
While this may seem a bit extreme, being
vigilant in the upkeep of your G-1TM 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 G-1TM. In
fact, the G-1TM. has been tested and proven
to function underwater. However, long-
term exposure to moisture can cause rust
damage to some of the G-1TM’s screws, so
if your G-1TM should become waterlogged,
remove the barrel, stock 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 G-1TM ONLY with
GR33SETM pneumatic grease. Use fresh,
high quality paintballs for best performance.

BARREL BLOCKER IN USE
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 G-1TM 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 G-1TM 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 G-1TM is on a “live” paintball eld and all persons
involved are wearing proper paintball protection.
The G-1TM is a high performance tournament grade paintball marker. Its low-force bolt will often
prevent paintballs from being chopped if the hopper is not able to load paintballs as fast as the G-1TM is
being red. If you want to realize the G-1TM’s maximum repower potential, especially if it is upgraded
with a circuit board that utilizes an anti-chop eye for higher rates of re, 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 G-1TM.
The G-1TM 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. If the hopper is a tight t, a at bladed screwdriver may be used to
further spread the gap in the feedneck clamp, provided the clamp screw has been loosened enough.
The G-1TM may also be congured so that the hopper is located to the right, left, or directly above the
center of the marker. See the Advanced Maintenance Section of this manual for instructions to change
or reposition the feedneck.
