Abstract: 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.

Abstract: The present invention provides a pistol with a frame having a rear grip, a trigger facility forward of the grip and an upper surface. An elongated slide is connected to the frame and operable to reciprocate along the upper surface. The frame defines a rear recess open at the upper surface. An insert is included having a major portion removably received in the rear recess and having a frame rail extending from the major portion above the upper surface. The frame rail is adapted to connect with the slide to constrain reciprocation.

Abstract: System for a multi-caliber self-loading action. Specifically, the system is comprised of a multi-position locking assembly and a self-regulating gas assembly. The multi-position locking assembly is comprised of a bolt carrier, a spring, a bolt, a lock, and a cam assembly. The cam assembly will interface between the bolt carrier and the bolt to rotate the bolt through the bolt carrier. The lock will interface with the bolt, to lock the bolt in at least one locked position based on the caliber of the round inserted. The self-regulating gas assembly directs gas from the gas regulation to at least one piston cup, which will then cause the piston to act on the multi-position locking assembly.

Abstract: A rifle platform with semi-automatic, select fire, and/or fully automatic shooting options uses a pistol cartridge. The rifle barrel includes an extension having a ramp for loading the cartridges and having a key way for the shell extractor. The magazine of the rifle is mounted to the lower receiver so as to load the cartridges in a direction perpendicular to the rifle barrel. The magazine follower automatically locks the bolt after the last cartridge is fired. The bolt and bolt carrier are integrally machined, and fully enclose the cartridge to preclude out of battery firing.

Abstract: A noise suppressor for mounting on a distal end of a rifle barrel. The suppressor is made up of an inner core component and an outer sleeve component which is received about the inner core component, creating a gas-receiving chamber between the two. The inner core component an internally threaded, barrel receiving end which receives and engages the exteriorly threaded end of the rifle barrel in overlapping fashion, an oppositely arranged exteriorly threaded end, and a central bore between the two ends which allows the passage of a bullet when the bullet is fired, firing of the bullet also setting off hot exhaust gases in the central bore. The inner core component has window openings for exhausting hot gases from the inner chamber into the surrounding outer chamber and also has an exterior longitudinal region forward of the central chamber, the exterior region having a series of longitudinally aligned, upwardly extending teeth formed therein for diverting the hot, high speed gases contacting the upwardly extending teeth.
