This part of the manual is intended for players familiar with
the operation of paintball guns. It presents a quick overview
of the 68AUTOMAG.
 To ready the 68AUTOMAG for play:
- Insert the Barrel into the Main Body then twist the
Barrel 1/4 turn clockwise.
- Push the Safety Pin located behind the Trigger from
right to left to disengage. Check that the RED ring on
the Safety Pin is showing.
- Hold the paintball gun upwards. Squeeze and hold the
Introducing CO2 pressure to the
paintball gun will charge and
cock the system.
Do NOT use a siphon type constant
air tank. Liquid CO2 will damage
- Attach the CO2 source to the Back Bottle Adapter by
turning the Air Source clockwise.
- It is recommended to
lubricate any air source O-ring
with a little Lithium Grease
(White Grease) before attaching
the Air Source to the Back Bottle
- If the Air Source is a pin
valve constant air tank, rotate
the tank at least one full turn
after initial gas up.
- If the Air Source is a
constant air tank with an on/off
valve, open the on/off valve
fully after attaching.
- Release the Trigger.
At this point, the CO2 pressure
within the paintball gun will
push the Trigger Rod forward
against the Trigger with a loud
click. The paintball gun is now
cocked and armed.
Only fire the paintball gun in
areas where firing is permitted.
An excessively hard trigger pull
shows overpressure in the system.
Do NOT fire a paintball gun that
has excessive trigger pull.
- Dry fire the paintball gun several times in a safe
direction to seat the Regulator Piston and Regulator
Spring Pack properly.
- Push the Safety Pin located behind the Trigger from
left to right to engage. Check that the RED ring on the
Safety Pin is NOT showing.
- Attach the Elbow to the Ball Feed Tube, then insert
the Loader into the Elbow. Load the Loader with
.68 calibre paintballs.
- Chronograph the paintball gun velocity to meet the
field safety speed limits. Adjust the velocity by
turning the Regulator Nut with the Allen key supplied.
Turning the Regulator Nut clockwise increases the
velocity; counterclockwise decreases the velocity.
 The 68AUTOMAG, like any other paintball gun, can have problems
during play. Some problems are common to any paintball gun
while some are unique to the 68AUTOMAG. Solutions to any of
the common problems are not difficult.
 Simple problems that can occur are:
 Each of these problems is discussed and the solution(s)
underlined in the sections that follow.
- Poor Paintball Feeding;
- Bolt Stick;
- Air Venting;
- Total Shutdown;
- Velocity Drop Off;
- Liquid CO2 in the Paintball Gun;
- Cut Paintballs;
- Excessive Paintball Breakage;
- Double Feeding; and
- Spontaneous Barrel Leaks.
Poor Paintball Feeding
 Poor paintball feeding is usually caused by one or more of:
user technique, bolt blowback, elbow hangups or nubbin depth.
Explanations and solutions are:
- The 68AUTOMAG lacks recoil to shake the Loader and help
feeding. Occasionally shake the paintball gun gently
- The Loader provided can only feed at most 7 paintballs
per second. Control your rate of fire.
- Bolt Blowback helps feeding if the Loader is full but
can blow the paintball up the Ball Feed Tube when the
Loader is near empty. Keep at least 20 paintballs in
- Paintballs may hang up on edges or corners in the
Elbow. Make sure there are no sharp corners or edges
in the Elbow. Sand the inside of the Elbow if
- The Nubbin is adjusted to prevent two paintballs from
feeding into the breech. If the Nubbin is in too far,
oversize paint will not feed. Adjust the Nubbin
 The Bolt can stick forward causing the Trigger to lock. Bolt
Stick is due to either paint chips wedging between the Bolt
and the breech or, when degassing the paintball gun, firing
the last few shots with no CO2 pressure. When the Bolt sticks
forward, the Trigger will not come forward. To clear Bolt Stick:
- Unload the paintball gun;
- Remove the Barrel;
- Push the Bolt back with a wooden rod until the Trigger
Air venting out the back of the
Regulator Nut shows that the
internal Blow Off Valve is
venting an overpressure in the
 Air Venting can occur from the rear of the Regulator Nut due to
an overpressure in the system or liquid boiling off in the
Valve Body or Regulator. The paintball gun is shooting at
approximately 340 fps. ALWAYS check the velocity any time the
Blow Off Valve vents to prevent injuries to players.
 Total shutdown is caused by an empty Air Source. The 68AUTOMAG
gives little indication that it is running out of gas. When a
noticeable velocity drop occurs, only 20 to 30 shots remain
till total shutdown. Change the Air Source.
Velocity Drop Off
 Velocity drop off can be caused by the Regulator being unable
to fill completely between shots, insufficient CO2 flow or a
near empty Air Source. Slow your rate of fire. Ensure the
Air Source is fully open. Change the Air Source.
Liquid CO2 in the Paintball Gun
 Liquid CO2 can enter the Air Chamber and, when expelled into
the Barrel behind the paintball, the CO2 boils instantly to
30 times its volume. The resulting shot will be above the
velocity setting. Depending on the volume of the liquid, the
speed may exceed 350 fps. The rapid boil off is known as
supercharging . The Blow Off Valve will NOT prevent
supercharging because the liquid is at normal pressure when
it enters the Air Chamber. Liquid CO2 also will cause all
the active O-rings to leak resulting in no velocity control.
To prevent liquid in the paintball gun:
- Never shoot at the ground because this allows liquid
CO2 to run straight into the paintball gun.
- Never overfill a constant air tank because a higher
than normal liquid level will drain liquid CO2 into the
- Keep the paintball gun at a warm temperature because a
cold Valve Body will stop the liquid CO2 entering from
boiling into a gas as designed.
- Never put a warm Air Source on a cold paintball gun
since the CO2 may condense into a liquid when the CO2
enters the Air Chamber.
 Paintballs in the breech being cut by the Bolt shows a
feed problem (See Para 6.).
Excessive Paintball Breakage
 A properly set-up 68AUTOMAG, using quality paintballs, will
break approximately 3-4 paintballs per 1000. Paintball
breakage is due to one of the following; physical impact of
the BOLT, CO2 blast or poor paint quality. Check the Foamie
located on the front of the Bolt for damage or debris.
Reduce the velocity to reduce CO2 blast. Try a different
batch of paintballs by changing the colour or the brand of
 Double feeding occurs when two paintballs feed into the
breech simultaneously. The size and shape of paintballs may
vary. Temperature and humidity will affect both size and
shape. The Nubbin is designed to prevent double feeds.
Adjust the Nubbin inwards.
Spontaneous Barrel Leaks
 Spontaneous barrel leaks are usually short lived but are an
annoyance on the field. Poor lubrication of the Power Tube
O-ring or ice crystals on the Power Tube O-ring are the
cause. An unlubricated o-ring will usually seat itself after
a few shots. If ice is causing the leak, continued firing
will only prolong the problem. Pause long enough to warm up
the Power Tube O-ring.
If the Barrel continues to leak
and the action of the game
prevents repairs, hold the
Trigger down to stop the leak and
allow the Power Tube O-ring to
warm up. When ready to fire,
release the Trigger and fire
quickly. Expect lower paintball
velocity since the Air Chamber
will not have time to fill fully.
