摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

摘要： A method of modifying a .45 ACP pistol having a slide and a receiver defining a magazine well includes the steps of reducing the size of the magazine well and shortening the slide. The slide includes a breech face and a proximal end and the magazine well includes a front wall and spaced therefrom a rear wall. Reducing the size of the magazine well involves moving the rear wall closer to the front wall. Shortening the slide involves removing material from between the breech face and the proximal end. The shortening of the slide generally corresponds to the size reduction of the magazine well.
