Abstract
Provided is a firearm gas operating system. A gas block includes a cylinder housing. A gas actuation piston in the cylinder housing reciprocates between forward and rearward positions and has a head portion with a recess. A switchable gas control valve is insertable into the forward end of the cylinder housing and includes a central passageway open at forward and rear ends. A tubular extension open at opposite ends extends axially rearward from the gas control valve and is configured to be received by the piston head portion recess. Gas pressure diverted from the barrel causes the piston to reciprocate from its forward position, where the head portion recess extends over the tubular extension, to its rearward position, where the head portion recess disengages from the tubular extension, allowing gas to exhaust through the tubular extension and forward end of the control valve to atmosphere.
