摘要： A push rod operating system for an AR-15/M-16 rifle includes an AR-15/M-16 rifle having a barrel coupled to an upper receiver, a bolt carrier carried by the upper receiver, and a mechanical key coupled to the bolt carrier. A gas block is coupled to the barrel, the gas block having a bore therethough. A rod tube extends from the gas block in communication with the bore, toward the upper receiver. A gas plug has a gas chamber closing the bore of the gas block opposite the rod tube. A discharge gas pathway permits discharge gasses to enter the gas chamber from the barrel. A piston rod element is carried in the rod tube with a piston portion thereof reciprocally received within the bore of the gas block and movable between a first position abutting the gas plug to define an operating volume, and a second position. A push rod element is carried by the rod tube and engages the mechanical key and the piston rod element.
