Introducing the ARS Gas Piston System!
Our new State of the Art Piston Operating provides a reliable, positive cycling direct impingement, 2-stage gas piston system. The type of operating system used on advanced weapons like the FN SCAR, H&K G36, & H&K416. Also the highly reliable, classic FAL & AK-series rifles, now in an AR-15. Runs cooler, smoother, and performs more reliability, with less wear & easier maintenance. Because the gas no longer vents inside the receiver, fouling & carbon buildup are greatly reduced, making maintenance easier with less frequent disassembly of the receiver for cleaning. Less fouling & 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 topside of the one-piece bolt carrier redesigned specifically to work with the piston system.
