Abstract

A lightweight one man portable automatic gas-operated weapon system for intry use having symmetrical forces applied to recoiling parts by use of two parallel gas pressure actuated rods acting in unison. An integral sprocket feed system is actuated by the recoiling parts and avoids gross asymmetrical force movements about the weapon's center of gravity resulting from shifting ammunition weight. A dual tube receiver and dual gas system is featured in the weapon. Major weapon subassemblies comprising modules are operatively interrelated to facilitate replacement during field use of the weapon.
