A bullpup shotgun which ejects shells from the bottom of its action has a reciprocable cover which, when in a closed position, overlies the breech end of the shotgun's barrel. When in an open position, the cover is in spaced relation to the barrel breech end, allowing access to the shotgun's action to clear an ammunition feed malfunction. The cover is mounted on a butt stock, and is slidable or rotatable relatively to the shotgun's butt stock to effect motion of the cover between the open and closed positions.

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 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.

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.

Firearm ejectors and receivers and firearms including such firearm ejectors are disclosed. An example ejector for a firearm includes a body including a projection extending therefrom, the ejector to be movably coupled to a receiver of the firearm to enable the projection including an engagement surface to be disposed in a movement path of a breechblock, the engagement surface to be engaged by a cartridge casing during a recoil process to enable the cartridge casing to be ejected from the firearm; and a spring to bias the body relative to the receiver, the body to be movably relative to a longitudinal axis of the receiver upon impact with the cartridge.
