MANUAL FOR

PCR/AR RIFLES

620-626 Old Pacific Hwy SE

Olympia, WA 98513

(360) 459-7940

WARNING

To avoid accidental firing, BE SURE WEAPON IS CLEAR. Failure to do so could

result in serious injury or death.

Be sure the cam pin is installed in the bolt group. If it isn’t, your rifle can still fire

and will explode causing injury or death.

DO NOT exchange or switch bolt assemblies from one AR-15 to another. It could

cause damage to both you and your rifle.

DON’T OVERHEAT YOUR AR-15 BARREL. Sustained firing of the AR-15 will

rapidly raise the temperature of the barrel to a critical point.

Firing 140 rounds, rapidly and continuously, will raise the temperature of the bar-

rel to the COOKOFF POINT. At this temperature, any live round remaining in the

chamber for any reason may detonate (cookoff) in as short a period as 10 seconds.

If the cookoff point is felt to be possible, clear your weapon and allow it to cool.

Sustained rate of fire for the AR-15 is 12-15 rounds per minute. This is the actual

rate of fire that this weapon can continue to deliver for an indefinite length of time

without seriously overheating.

Sustained rate of fire should never be exceeded except under circumstances of

extreme urgency.

If your bolt fails to unlock and you try to free it by banging the buttstock on the

ground, keep clear of the muzzle.

If there’s water in the barrel, don’t fire the rifle. It could explode.

If you experience a noticeable difference in sound or recoil, STOP FIRING. Either

condition could indicate an incomplete propellant bum and a bullet still in the

bore. Retract bolt slowly and remove fired cartridge case. Clear weapon and check

for unburned powder grains in the receiver or bore, and for a bullet in the bore.

Remove unburned propellant or bullet from bore before resuming firing or barrel

could explode. If bullet is lodged in bore, take your rifle to a qualified gunsmith.

If your rifle stops firing with a live round in the chamber of a hot barrel, remove

the round quickly. If you cannot remove the round within 10 seconds, point the

rifle in a safe direction and wait 15 minutes. In this way, you won’t be injured by a

possible ammunition cookoff, which could happen within 10 seconds after contact

with a hot chamber. Clear rifle.

Use only authorized ammunition that is manufactured to U.S. specifications.

Please read this manual carefully before attempting to use your AR-15.

Technical Principles of Operation

NOTE:

Magazine may be loaded with bolt

assembly open or closed.

Place selector on SAFE

Insert loaded cartridge magazine

in magazine well and chamber a

round.

Face the target, move the selector

lever from SAFE to FIRE and

place the rifle to your shoulder.

Align the front and rear sight with

the target and squeeze the trigger.

Squeezing the trigger releases the

firing pin and allows it to impact

the primer on the round.

The primer ignites the propellant

in the round.

7.Gas from the burning propellant pushes the projectile along the barrel of the

rifle.

8.The rifling in the barrel causes the projectile to rotate, which provides stability

during flight to the target.

9.When the round reaches the approximate end of the barrel, expanding gases

from burning propellant pass out through gas port and into gas tube. Gas goes

into bolt carrier assembly, ejects old cartridge, and chambers a new round.
