摘要： A two piece upper receiver for a firearm including a first piece having a front end, a rear end, a top, and a bottom, the first piece constructed to operatively carry a bolt carrier and bolt, and to have a barrel coupled to the front end. The bottom is constructed to have a lower receiver coupled thereto. The first piece includes a backbone extending along the top between the front end and the rear end, the back bone having upwardly directed indexing surfaces. A second piece overlies the backbone and includes mating surfaces engaging the indexing surfaces, aligning the second piece with the first piece. A receiving structure is opposite the mating surfaces for receiving accessory devices mounted thereon. Fasteners fixedly attach the second piece to the first piece to form a complete upper receiver.

摘要： In various embodiments, a firearm assembly devices, systems and methods are provided. The firearm assembly can comprise a barrel and a chamber comprising a channel. The chamber may have a first length. The chamber may comprise an internal wall defining an internal cavity. The chamber can also couple to the barrel. The channel can be defined in the internal wall of the chamber. The channel may have a second length that is shorter than the first length. In various embodiments, the firearm assembly may be a component of a rotating bolt firearm. In various embodiments, internal cavity of the firearm assembly has a profile configured to receive a cartridge. The devices systems and methods described herein reduce common rotating bolt firearm failure modes by encouraging case ejection, compression, and/or contraction.

摘要： A push rod operating system for an AR-15/M-16 rifle includes an AR-15/M-16 rifle having a barrel coupled to an upper receiver, a bolt carrier carried by the upper receiver, and a mechanical key coupled to the bolt carrier. A gas block is coupled to the barrel, the gas block having a bore therethough. A rod tube extends from the gas block in communication with the bore, toward the upper receiver. A gas plug has a gas chamber closing the bore of the gas block opposite the rod tube. A discharge gas pathway permits discharge gasses to enter the gas chamber from the barrel. A piston rod element is carried in the rod tube with a piston portion thereof reciprocally received within the bore of the gas block and movable between a first position abutting the gas plug to define an operating volume, and a second position. A push rod element is carried by the rod tube and engages the mechanical key and the piston rod element.
