An adapter for an M240 machine gun to position the trigger housing assembly distally forward as well as an M240 machine gun with the trigger housing assembly positioned distally forward from the proximal end of the receiver.

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.

A rife includes a receiver and a bolt body at least partially disposed in the receiver and including a body axis. The bolt body is discretely (1) rotatable about the body axis within the receiver and (2) axially slidable along the body axis. The rife also includes a bolt handle coupled to the bolt body so as to discretely (1) rotate with the bolt body about the body axis and (2) move with the bolt body along the body axis.

A safety device for redirecting spent ammunition cartridge cases away from a rifleman or bystander as they are ejected from the ejector port of a semiautomatic or automatic rifle. In a first embodiment, the center mounted embodiment is preferred. The presented device includes a mounting clamp assembly, mounting rod and pivoting deflector. The deflector can be pivoted to permit the ejection pattern desired by the rifleman. In a second embodiment, the side mounted assembly, the mounting clamp assembly is attached to the right hand side rail of the forearm and barrel assembly. In the third embodiment, rear mounted assembly, the clamp mounting assembly is installed at the rear of the upper receiver rail. In a fourth embodiment, forward mounted assembly, the mounting clamp assembly is mounted on the forearm upper accessory mounting rail. All embodiments described herein apply to a left-handed version of the rifle.
