Manual

Turn the gas regulator on the gas block so that the arrow on the knob points to the letters

“SUPP” when firing with the active sound suppressor attached to the rifle.

For firing without a suppressor, or with the dummy suppressor installed, turn the

knob so that the arrow points to “NORM”. DO NOT fire the rifle with a suppressor

when the regulator is set to the “NORM” setting. The rifle will function too fast, and is

subject to unreliable operation and excessive wear.

If the gas regulator is hard to turn with finger pressure alone, or is hot from firing, the rim

of a fired cartridge case may be used as a tool.

WARNING: DO NOT USE A LIVE CARTRIDGE TO TRY TO TURN A HOT

GAS REGULATOR KNOB. THE HEAT COULD DETONATE THE PRIMER

To properly maintain your SuperSASS gas regulator system, there are a few steps that

must be performed. If you plan on firing the SuperSASS rifle with the suppressor on the

rifle, the gas regulator MUST be set to the SUPP position. If the suppressor is removed,

the gas regulator must be in the NORM position.

CAUTION: Firing the SuperSASS wieh the gas regulator in the NORM position

while the suppressor is in place could cause damage to your rifle. If the SuperSASS

is fired mainly with a suppressor, the gas regulator should be cleaned every hundred

rounds. This is done by removing the suppressor, placing the regulator in the NORM

position, and firing a single twenty round magazine through the rifle to ensure the NORM

position gas port remains open. Prolonged firing in either the suppressed or unsuppressed

mode without cleaning may cause the gas regulator to become frozen or difficult to

move. During the cleaning of the rifle, a small amount of oil or penetrate into the back of

the regulator, where the gas tube cylinder meets the gas block, will help the regulator to

move properly.

ZERO THE RIFLE WITH THE SUPPRESSOR.

The normal disruption of muzzle gases and the added weight of the suppressor on the

barrel will normally shift the zero of a rifle. This shift may vary with different cartridges.

Establish both the suppressed and unsuppressed zero of the rifle and use them as

appropriate.
