摘要： A firearm can have a backbone, a barrel, a swinging wedge, and a barrel latch, in accordance with one or more embodiments. The barrel latch can be in mechanical communication with the swinging wedge. The barrel latch can have a first position and a second position and the swinging wedge can be configured to maintain attachment of the barrel to the backbone when the barrel latch is in the first position and is configured to release the barrel from the backbone when the barrel latch is in the second position. Thus, the firearm can provide quick barrel changes. Other features enhance the reliability and utility of the firearm.

摘要： A combination metal/polymer upper receiver for use in a rifle, with the upper receiver attachable to a lower receiver and to a barrel. The upper receiver comprises a polymeric upper receiver housing defining a chamber. The polymeric upper receiver housing is adapted to engage with mounting features on the lower receiver to attach a lower receiver to the upper receiver at a first connection. A metal insert is secured within the polymeric upper receiver housing and is adapted to engage the barrel. The metal insert further includes an extended member embedded within the polymeric upper receiver housing such that the extended member receives the impact from a bolt carrier group residing within the chamber. An optional metal gas tube channel is located along an upper internal surface of the polymeric upper receiver housing and extends the length of the polymeric upper receiver housing.

摘要： A firearm can have a bolt having a plurality of locking lugs that are configured to have a shear area that is at least approximately 1.3 times that of a standard M16/M4. A piston can be formed on the bolt and can have a plurality of rings that are configured to cooperate with the piston to mitigate gas leakage past the piston. Each of the rings can have a key formed thereon and a gap formed therein such that the gap of one ring is configured to receive at least a portion of the key of another ring. The bolt carrier can have a double cut cam.

摘要： A direct gas impingement operating system for an automatic or semi-automatic rifle. The direct gas impingement operating system has a gas block fitted to a barrel having a bore, the gas block in communication with the bore. A gas sleeve is located in the gas block, the gas sleeve in communication with the bore through the gas block. A bolt assembly having an impingement cylinder and a gas line is fitted to the sleeve in communication with the bore through the sleeve and the gas block, the gas line further in fluid communication with the impingement cylinder. Gas discharged from a fired cartridge displaces the impingement cylinder displacing the bolt assembly. The sleeve and the gas line are removable from the gas block without removal of the gas block from the firearm.

摘要： An improved firearm having a barrel coupled to an upper receiver where the receiver includes a passageway extending generally parallel to the longitudinal axis, and a guidance feature extending along the passageway generally parallel to the longitudinal axis. The firearm also includes a lower receiver coupled to the upper receiver and a recoil spring assembly comprising a mating attachment structure and a disassembly button disposed on a lateral side of the upper receiver. The mating attachment structure is attached to an attachment structure of the lower receiver to attach the lower receiver to the upper receiver. Actuation of the disassembly button detaches the mating attachment structure from the attachment structure to detach the lower receiver from the upper receiver.
