The first method, called a " gas piston ," uses the high pressure gas ported from the barrel to drive an enclosed piston back against an operating rod or linkage ( they are often one piece ), which in turn unlocks the bolt and drives it rearward, ejecting the spent case and cocking the hammer or striker spring.
