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.

There is provided an automatic firing apparatus, and a method for operating the automatic firing apparatus, the apparatus comprising a trigger actuator for automatically firing bullets contained in a magazine of a firearm; a magazine release actuator for releasing an empty magazine from the firearm; a magazine bank for storing a bullet magazine inside the firearm; and a magazine loading actuator for loading a new magazine inside the firearm from the magazine bank. There is further provided a magazine bank apparatus for use with a firearm comprising a magazine bank base having a plurality of slots adapted to receive and store bullet magazines; and a magazine load actuator adapted to be automatically triggered for loading a bullet magazine among the stored bullet magazines inside the firearm.

Disclosed is a novel cartridge feeding system for a gun, relating to the technical field of guns. The system comprises a gun barrel, a chamber, a grip, and a trigger set. A feeding rail is arranged between the grip and the chamber, the trigger set is located at the bottom of the feeding rail, and one end, away from the grip, of the trigger set is provided with a magazine. The upper side of the magazine is connected to the inner bottom of the feeding rail, a rotatable feeding ramp is hinged to the bottom of one end, close to the feeding rail, of the chamber, a bolt is movably arranged in an upper half part of the feeding rail, and a movable cartridge extraction/pushing hook is hinged to the bottom of one end, close to the chamber, of the bolt.

A method of feeding rounds of linked, or un-linked, ammunition to a gun includes a motor-driven chain drive which rotates about a track. A rotatable feeder engages the ammunition to feed an ammunition round into a round extractor/retractor. A rotatable round positioner receives an ammunition round from the round extractor/retractor, and rotates it to a firing position. A main geneva wheel, mounted near the chain drive, is sequentially engaged by first and second drive rollers, secured to the chain drive, for being periodically rotated thereby. Drive pins of the main geneva wheel sequentially engage radial slots in a belt/round feed geneva wheel and a round positioning geneva wheel for timed rotation thereof to synchronize the operation of the round feeder and round positioner.

A loadable ammunition magazine for use with a sporting firearm includes a housing defining a cartridge-loading compartment and a follower compartment, a cover that alternately covers and reveals the cartridge-loading compartment, and a follower that urges cartridges in the cartridge-loading compartment towards a mouth of the magazine. A locking assembly prevents the magazine from being detached from the lower receiver of the firearm without disassembly of the firearm action designed for use with AK-47-style rifles having stamped receivers, the locking assembly comprises a locking bar including a horizontal lower flange that is secured by a threaded fastener to the top wall of the magazine housing and a horizontal upper flange that rests on the cross rivet of the receiver. In another embodiment, designed for use with AK-47-style rifles having machined receivers, the locking assembly comprises a locking bar including a horizontal upper flange that is secured by a threaded fastener to the top wall of the magazine housing and a horizontal lower flange that rests on the bottom wall of the receiver.
