摘要： In a machine gun having a gas-actuating system including a gas cylinder responsive to gas pressure generated by the discharge of a round and including a receiver and a barrel mounted therein having a predetermined bore and a muzzle, a novel gas evacuation means, a novel barrel extension means and a novel gas seal means all for removing exhausted gas from the area surrounding the machine gun receiver, gas cylinder and receiver. The novel gas evacuation means, mounted on the gas cylinder and along the barrel, is in communication with the gas-actuating system for removing exhausted gas therefrom and conveying said exhausted gas for discharge at a location remote from the muzzle; the novel barrel extension is attached to the muzzle of the barrel, has a bore greater than the barrel bore for removing exhausted gas from the muzzle and conveying said exhausted gas for discharge at a location remote therefrom free from interference with the operation of the gun mechanism; and the novel gas seal means includes an obturating nut and sealing collar provided in the gas-actuating system for preventing exhausted gas from passing rearwardly therethrough and escaping from the receiver.
