    摘要： A magazine of a pistol for cartridges with a case rim, having a hollow magazine body for accommodating the cartridges in two vertically offset rows, a base plate, a feeder, which is guided in a displaceable manner in the magazine body, and a compression spring between the feeder and the base plate, wherein the upper end region of the magazine body forms a narrowing, in which the two rows of cartridges are guided together to form a single row. In order to ensure a reliable feed of the cartridges despite the case rim, in the longitudinal center the side walls have inwardly directed beads which run over the entire height of the side walls and merge, in the upper region, into converging guide ribs, and the feeder forms a bearing surface, which is convex in the longitudinal direction and on which a cartridge located thereon can alter its angle of inclination in relation to the horizontal.

    摘要： A locked breech rotating bolt pistol caliber operating system for use with a semi-automatic or fully automatic firearms is described that is retro fit capable and is compatible with many existing AR15 type lower receivers that utilize pistol caliber magazines. The operating system includes an upper receiver that includes a fixed ejector to eject spent casings to minimize the likelihood that the firearm will jam.

    摘要： Disclosed is a semi-automatic firearm which has a configuration generally similar to a known form of submachine gun insofar as it comprises an elongate receiver, a pistol grip extending downwardly from the receiver and forming a housing for a cartridge magazine and a trigger mechanism and sear located forwardly of the pistol grip. The firearm operates on the blowback principle with closed breech type operation and employs a slidable bolt and separate slidable firing pin striker mechanism within the receiver, with the bolt being freely slidable and the sear operating on the striker mechanism. The trigger mechanism only has a semi-automatic and a safety setting and the bolt face has a feed lip of a design which causes the firearm intentionally to jam under certain abnormal operating conditions.

    摘要： There is described a cartridge injector assembly which serves to properly position the next cartridge to be inserted into a firing chamber of a weapon. The injector includes a moveable arm which is caused to coact with a cartridge just beneath the next cartridge and forces that cartridge and therefore the next cartridge into a position to assure that the cartridge will, in fact be properly inserted. This is accomplished by a slotted magazine, which slot accomodates the moveable injector arm and which arm is forced into the magazine during the return of the weapon to a rest position from a recoil position after a firing.

    摘要： The machine gun of this invention features a bolt assembly reciprocably mounted within a receiver and removably maintained within the receiver by a single latch mechanism, and a fire control group supported for reciprocation on the receiver between a forward charging position and a rear firing position, the fire control group including a sear releasably holding the bolt assembly in cocked condition, the fire control group having a releasable latch and a trigger pivot shaft mounted for movement laterally of the receiver and serving as a safety when the fire control group is in rear firing position.
