CAUTION
• Read the entire manual before using the Griffin.
• The Griffin is not a toy. It can cause serious injury or death.
• Wear approved eye and head protection, even when test firing.
• The compressed air source used with the Griffin can cause serious injury or death.
• Sale or use of the Griffin is not intended for individuals under the age of 18.
• The Griffin is to be used only as described in this manual.
• Fire only 0.68 caliber paintballs from the Griffin.
• Check the velocity of your Griffin before each use. Not to exceed 300 fps.
• The Griffin can fire when dropped.
• Keep the Griffin unloaded and unpressurized when not in use.
• Install a barrel plug in the barrel when not in use. (One is included.)
• Replacement barrel plugs are available from your ACI dealer.
• Handle the Griffin as if it is always ready to fire. It recocks during firing.
• The Griffin can be dangerous up to 200 yards (180 meters).
• Don’t shoot at opponents closer than 20 feet.
• Never shoot toward individuals not wearing approved eye and head protection.
• Never disassemble the Griffin while it is pressurized.

• Two very dangerous defects require immediate attention by your dealer or quali-
fied airsmith:
1. The air source bottle valve unscrews from the bottle.
2. The gun double fires (other than when you are running out of air).
• Do not modify your gun, especially your trigger assembly.

Air Source Installation
Once the Griffin is properly cocked with the safety on you can
pressurize it with C02, regulated compressed air or nitrogen. Only
after you understand how to handle it safely should you attempt to
pressurize your Griffin.
Proper Seating of Air Source
The bottle O-ring provides the seal, so just tighten the bottle until
it is snug. You should hear a brief hiss as the bottle valve opens
during the last 1/2 turn. Over tightening can damage the Griffin.
If a leak persists, replace the bottle O-ring.
CAUTION
Depressurize the Griffin (remove the bottle) unless you
are about to use it. Do not unscrew the bottle from the
bottle valve; you may turn the bottle into a rocket!
OPERATION
Before pressurizing, check that the Griffin is cocked but not
loaded. If not cocked, air may leak until the cup seal seats.
Also, if not cocked the Griffin can fire as it is being pressur-
ized.
Cocking
To cock the Griffin, pull the cocking pin rearward until it latches.
Be careful, if you let go before it latches, the Griffin can fire. DO
NOT DRY FIRE THE GRIFFIN (To pull the trigger, the safety
must be disengaged.)
4
Loading
Install a 7/8 elbow with loader on the ball feed tube. Following
the directions of the manufacturer, fill the loader with .68 caliber
paintballs.
Trigger Safety
The Griffin has a trigger safety to help prevent accidental firing.
With the Griffin pointing away from you, engage the safety by
pushing it to the right. When the safety is toward the left the
Griffin can then be fired. The safety may not engage unless the
Griffin is cocked. Remember, the only time the Griffin is truly
safe is when it is unloaded and depressurized
Firing
To fire the Griffin, point it in a safe direction, away from yourself,
and pull the trigger. The trigger safety must be off; that is to the
left. Fire the Griffin as often as you like with air, with or without
paintballs in it. This helps break it in and makes it operate
smoother.
Uncocking
Before uncocking, unload. Rotate your gun to the side so paint-
balls in the chamber and elbow roll back into the loader. Take a
couple of shots in a safe direction to insure that the barrel is
empty. If you uncock with a ball in the chamber, it will be forced
forward into the barrel. Later when you recock, a second ball will
enter the chamber. If two balls are fired at once, they may break.
To finish uncocking, unscrew the air source, pull back the cocking
pin, pull the trigger and let the assembly move forward slowly.
DO NOT DRY FIRE THE GRIFFIN. (To pull the trigger, the
safety must be disengaged.)
Air Source Removal
Once the Griffin is properly uncocked with the safety on you can
depressurize it. To depressurize the Griffin, slowly unscrew the
air source paying special attention to the bottle valve. DO NOT
UNSCREW THE BOTTLE VALVEFROM THE BOTTLE.
UNSCREWING THE VALVECOULD CAUSE SERIOUS
INJURY OR DEATH.
WARNING
Avoid dry firing (without air) — damage to the
valve body, stop pin, and cup seal can occur.

TUNING YOUR GUN
Regular tuning is essential. But don’t waste time trying to tune a
gun which is:
• Dirty or poorly lubed
• Has a damaged striker O-ring
• Low on air
• Has the wrong O-rings installed
Check velocity to ensure it is not too high. It was set to 260 fps
at the factory, but it will change over time, and with temperature. Velocity Adjustment Procedures
Before adjusting velocity make sure the striker plug is screwed in
all the way. Your gun must be properly lubricated and free of all
dirt and debris.
Insert 1/4 hex wrench (provided) into the velocity adjustment
screw located in the striker plug as shown in the diagram below.
Turn clockwise to increase velocity. Turn counter clockwise to
decrease velocity. Check your velocity on a reliable chronograph
every quarter turn until desired velocity is reached.
CAUTION
Do not adjust velocity with the striker plug
partially unscrewed. If it is later screwed back
in, the velocity may be dangerously high.
PLAY SAFE!

FIELD MAINTENANCE
Before each use, your gun must be cleaned, lubed, and tuned.
Field Stripping
To field strip your gun (refer to illustrations):
1. Depressurize gun (remove air source)
2. Unload gun.
3. Uncock gun.
4. Unscrew barrel.
5. Unscrew bolt plug.
6. Pull cocking pin straight out from gun.
7. Remove bolt from front or rear of gun.
8. Swab bolt chamber back to front.
Reverse order for reassembly.

MAINTENANCE
AIR SOURCE MUST BE REMOVED BEFORE
ANY MAINTENANCE CAN BE PERFORMED
Barrel
To clean the barrel, unscrew it from the main body and swab back
to front. When paintball gelatin residue builds up, clean with
warm soapy water or rubbing alcohol. Residue build up hurts
accuracy.
Upper Chamber
Field strip as described on page 7 and use warm soapy water or
rubbing alcohol where needed to clean the rest of your Griffin.
Remove the bolt O-rings to remove paint and dirt build up from
the O-ring grooves.
Keep the bottle valve and adapter clean. Dirt entering here can
destroy the cup seal or valve body in one shot.
Lower Chamber
To clean the lower chamber perform steps 1-8 on page 7, then
remove striker plug assembly, striker spring and buffer.
Remove front and rear trigger housing screws and washers and
remove trigger housing. (Notice front screw is longer with a pilot
on it to secure the valve body.)
Slide striker out the rear of the gun. If needed, insert a small
object into the bottom slot of the main body, to assist in sliding
the striker out the rear of the gun.
Clean all major components of the gun.
Inspect all O-rings and replace as needed.
Apply AIRLUBE upon assembly of all moving parts.
Reassemble parts in reverse order, making sure to include trigger
housing washers. Be very careful not to force parts back together,
or permanent damage may occur.
The following parts should not be removed for
routine maintenance:
Cup Seal And Valve Body
Easily damaged when removed. In clean conditions these have
lasted for more than 250,000 shots. If exposed to dirt, the cup seal
will wear rapidly.
Reservoir Plug O-rings
Usually damaged only during removal
