Abstract

A compact firearm of the bull pup configuration, capable of operating in the semi-automatic, burst, and full automatic modes with an improved structure for mounting a sight or sighting device using bosses on the top of the receiver, which are received in matching recesses on the bottom of the sight or sighting device, so that the sight or sighting device may be placed directly upon the receiver in its intended position without any need of sliding engagement. Once placed, the sight or sighting device is fixed to the receiver by means of rotatable fasteners captured on the sighting device.

Abstract

An autoloading gas operated firearm of the 'bull pup' configuration capable of semi-automatic and automatic fire. Provision is made for quick release barrel interchange; and, a barrel with an integrally formed suppressor with internal discharge/venting of the gas operating chamber is described. The surfaces of sliding engagement with the bolt and bolt earner are hard coated for wear resistance making lubrication unnecessary. The sight structure is positively registered. The sight retaining knobs may be tightened with a cartridge case. The sliding surfaces of the receiver and bolt carrier are fluted for dirt collection; and, the bolt carrier tubes and stock are provided with water drain holes enabling ready firing after water immersion. A safety is described on opposite sides of the firearm with all-around readily visible indicia of firing status. The magazine engagement is uniquely configured to prevent usage of non specific ammunition.
