Abstract
A gas operating system for a firearm comprises a gas block defining a cylinder, a discharge gas vent coupled to the cylinder near a proximal end of the cylinder and a discharge gas inlet configured for pneumatic coupling with the barrel of a firearm near the proximal end of the cylinder. A piston in the cylinder is movable from a rest position distal of the discharge gas vent and the discharge gas inlet against the action of a return spring by discharge gas from a barrel of a firearm pneumatically coupled to the discharge gas inlet. A regulator is pneumatically coupled to the discharge gas vent to selectively control the flow of discharge gas from the discharge gas vent to modulate a volume of discharge gas advancing the piston. A diffuser may be provided pneumatically coupled to the regulator for diffusing any audible or visual report.
