An adapter for an M240 machine gun to position the trigger housing assembly distally forward as well as an M240 machine gun with the trigger housing assembly positioned distally forward from the proximal end of the receiver.

A left handed handgun which allows the use of conventional right handed unmodified magazines. The handgun assembly is adapted for left handed operation including the frame, slide, ejector, firing pin stop area, and extractor to accommodate the left handed user and eject empty cartridge cases away from the left handed user.

An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearms gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pins annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end and an extractor recess. The extractor recess is constructed to accommodate an enlarged extractor claw while not undercutting the bolt lugs adjacent thereto. The extractor engages approximately 57% more of a seated ammunition cartridges rim as compared to some prior art AR15/M16 type extractors used with automatic firearms chambered in 6.8SPC. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

The extension nozzle is designed to receive a portion of the host firearm's gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pin's annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end. The extractor recess is constructed so that the face of the bolt is round and the adjacent lugs fully supported. The extractor engages approximately 17% more of a seated ammunition cartridge's rim as compared to the prior art AR15/M16 extractor. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

In an extractor device (100) mounted in a breech (300) section of a slide with a lower part with functional elements for interaction with an upper region of a grip part (200) of a firearm with an extractor (110) mounted rotatably about an axis of rotation with an extractor claw (111) provided in the region of an end of the extractor (110) close to the barrel (210) of the firearm and a guide element (112) arranged in the region of an end of the extractor (110) remote from the barrel (210) of the firearm and interacting with an extractor spring (120) biasing the extractor (110), in order to limit a rotational movement of the extractor (110) by contacting a cartridge (400) newly supplied from a magazine. The guide element (112) is biased in the direction of a control link (130) by the extractor spring (120) arranged in an inner blind hole (113) of the extractor, said control link being configured in an extractor pocket (310) in the breech section (300) and forming a bearing of the extractor.

A firearm includes a bolt mechanism with a bolt configured to receive a firing pin assembly and a bolt head assembly. The bolt head assembly includes a pivoting bolt head and an extractor. The extractor is positioned relative to the bolt such that substantially all forces applied by the extractor to the bolt mechanism are reacted within the bolt head assembly. A biasing member or element can urge a claw portion of extractor towards a distal end of the bolt head.
