As previously explained, never rely on your
shotgun’s mechanical “safety” devices as the
sole provision for safety.
THING YOU DO NOT INTEND TO SHOOT.
Always treat your shotgun, even when
unloaded, with the respect due any loaded,
ready-to-fire firearm.
NEVER POINT YOUR SHOTGUN AT ANY-
Assembly of Barrel and Gas
System Components
CHECK YOUR GUN CAREFULLY TO BE
ABSOLUTELY CERTAIN THAT THE
CHAMBER, FEED MECHANISM AND
MAGAZINE CONTAIN NO SHELLS.
The A-500G is delivered, in the box, with
the barrel removed and the forearm-with
the gas piston, sleeve bar assembly and
return spring inside-assembled on the
magazine tube. Perform the following steps
to assemble your A-500G and make it ready
for shooting.
1. Take the receiver in hand. First, lock the
breechblock rearward by pulling the op-
erating handle fully to the rear. Then re-
move the forearm from the magazine
tube by unscrewing the magazine cap
and sliding the forearm forward, off of
the magazine tube.
DO NOT SQUEEZE HARD ON THE OPEN
REAR END OF THE FOREARM. TOO
MUCH PRESSURE COULD CAUSE THE
WOOD TO SPLIT.
