摘要: A gas operating system (5) for a firearm renders the firearm capable of firing a wide range of shot loads by passively and/or automatically compensating for different shot loads. The firearm includes a plurality of ports (210, 212, 214, 230, 232, 234) formed in the firearm barrel, and corresponding ports (110, 112, 114, 130, 132, 134) formed in a gas cylinder (100) of the gas operating system. The ports tap gases generated during firing which are used to cycle the firearm. When firing different cartridge loads, differing combinations of the ports are selectively at least partially blocked or otherwise obstructed by the cartridge casing according to the size of the cartridge.

摘要: An electrically-fired gun, of the type having a transverse sliding breechblock, has a recoil-operated mechanism for retracting the firing pin electrode tip behind the face of the breechblock during its opening and closing movements. A movable weight is connected by a rocker arm to the firing pin assembly, and is normally latched in place to hold the electrode tip in a retracted position. Manual release of the latch allows a spring to extend the electrode tip into a firing position. Recoil of the gun on firing results in a movement of the weight that retracts the electrode tip, and the parts are automatically re-latched in this position.

摘要: A firing pin block for a firearm of the type having a reciprocating bolt assembly including a breech bolt and slide block, a firing pin, and a pivotal locking block. The slide block and locking block have cam means which cooperate to pivot the locking block in and out of locking engagement with a recess in the barrel as the slide block is reciprocated to close and open the bolt. The operation of these cam means is coordinated with relative longitudinal displacements between the bolt and slide block so that, at any time the bolt is unlocked, the slide block prevents sufficient forward movement of an abutment on the firing pin to cause the firearm to discharge. This firing pin block is effective even though the firing pin spring and retaining pin may be broken, distorted, or missing: and forceably retracts the firing pin even if it is bent and jammed.

摘要: A cartridge extractor, comprising a resilient ring segment (21) formed with a claw (30), is mounted without a rivet in a recess (15) in the face of a firearm bolt (22). The bolt recess is formed with an arcuate clearance cut (31) and with radius cuts (27,28) at either end of the clearance cut. The ring segment has its free ends bent outwardly to form detent arms (23,24), which seat in the radius cuts to support the claw in position to engage a cartridge case as it enters the recess. This entry deflects the ring segment into the clearance cut. When the claw seats in the base of the cartridge, the ring segment is repositioned by the detent arms sliding back into the radius cuts. A pin (35). or other means may be added to prevent relative rotation of the ring segment, without interfering with its normal deflection.
