AR-15 Gas Piston

Because the gas no longer vents inside the receiver, fouling and carbon buildup are greatly reduced, making maintenance easier with less frequent disassembly of the receiver for cleaning. Less fouling and lower operating temperatures mean substantially reduced wear on bolt, carrier, and receiver interior for fewer malfunctions caused by worn parts. The cushioning effect of the piston reduces felt recoil to help you stay on target for fast, more accurate follow-up shots.

“Straight-line” design of the replacement gas block further ensures reliable operation by venting gas pressure directly on the operating rod. Rod transmits the force directly to a lug on the top side of the one-piece bolt carrier redesigned specifically to work with the piston system. Carrier and lug are machined from a solid billet of steel to eliminate breakage that can occur with a standard carrier modified for use with a gas piston system. Requires no permanent alterations to barrel or upper receiver. You can remove the piston system any time and reinstall the original parts.
