Abstract
An M16 type rifle capable of being fired in automatic or semi-automatic mode is disclosed utilizing a blow-back system with a forcing cone breech and a matching conical bolt face. The blow-back bolt assembly of the present invention allows elimination of the troublesome and easily fouled gas operating system of the conventional M16 rifle and further allows the rifle to be chambered for short low-pressure pistol cartridges such as the 45 ACP and the 40 S&W.
