ABSTRACT:
Firearm apparatus embodied in a semi-automatic, blowback operated rifle. The firearm includes a receiver made of two plates spaced apart to receive a bolt mechanism including a bolt mounted for reciprocal motion within a channel-shaped member; the operating spring for the bolt assembly is received in a slot within the bolt and is retained in place by the channel-shaped member. A unitary firing pin/extractor carried by the bolt functions as a firing pin and also provides multiple extractor functions. A simplified firing mechanism includes a hammer positioned to the rear of a cartridge magazine and operatively connected by a three-finger sear bar to a trigger mounted in front of the magazine. A safety mechanism is provided in conjunction with the trigger guard. Numerous components of this firearm apparatus provide multiple functions contributing to the economy and efficiency of the present firearm apparatus.
