A stop cylinder and piston assembly has both a firing piston and a piston used for both firing and return located on the same piston rod. The stop cylinder and piston assembly is designed with gas passages so that gas injected for firing purposes through a single aperture in the sidewall of a cylinder is applied to the rear surface of both the firing piston and the piston used for both firing and return. The system is reset by injecting return gas through a second sidewall aperture that is applied to the forward surface of the return piston. A vessel bumper is installed in the forward end of a chamber containing the firing piston to provide cushioning for the firing piston upon being fired.
