* Required Fields
Our Gas Piston Kits fit any AR-15 lower, but with a twist. Some upper receivers, like the ARAK 21, and .22 cailber conversions have their recoil system built in so they do not require a buffer tube and rear mounted recoil system. Other platforms like the SIG MPX and MCX can accept the stock.
Our Gas Piston Kit allows you to use your upper while remaining "featureless" in restricted states, or a more traditional rifle stock feel for people in "free" states.
