PRIOR TO INST ALLA TION

Make sure that your Griffin is unloaded and the air supply is disconnected. Due to the various air-input locations on markers, this kit does not

include the connection from the regulator to the ASA adapter. Your stock ACI Griffin bottomline hose will work with this kit.

INSTALLATION INSTRUCTIONS

1) Remove all bottom line connections from trigger frame.
Using the 5/32" Allen wrench remove the two screws that
connect the trigger frame to the main body. Gently separate
the trigger frame from main body.

2) Remove the striker plug and power spring, exposing the strik­er buffer. Remove the striker buffer (the buffer will be rein­stalled with the Sonic Conversion.)

3) Remove the connecting pin and release the bolt from the
striker. Remove the striker from the receiver. The bolt should
remain in the receiver to connect to the Sonic Conversion
striker.

THE SPORT OF PAINTBALL

The sport of paintball involves games in which opposing players attempt
to shoot each other with dye-filled projectiles called “paintballs”.
Paintball is a serious sport which makes rigorous demands on players’
physical and mental abilities. When played in a safe manner, it can pro­vide a rewarding experience not available in any other sport.

There are hazards in any active sport such as paintball. Serious injuries
are rare, but do occur.

A 0.68 caliber paintball moving at high velocity adds a special dimension
of hazard to paintball sports. At a minimum, it can cause pain and a bruise.
It can break the skin and cause bleeding. If it strikes an unprotected eye,
ear, or mouth it can cause blindness, deafness, or even death. If it strikes a
young child in a sensitive body area, it can cause crippling or death. This is
why proper safety gear for players, isolation of spectators from the play
area, and proper handling of paintball guns are absolutely essential.

The importance of always following safety rules, and the risk of serious
injury, require an adult level of maturity when using paintball guns. This is
why sale of the Griffin is limited to individuals 18 years of age and older.
