The long-stroke piston system includes a forward-accessible gas adjustment knob that allows adjustment without interference from top-rail-mounted optics, lasers, or other accessories. The piston system also vents excess gas to reduce fouling entering the action and to keep internal components cooler. The FRC compensator is designed for recoil and flash mitigation and is compatible with PWS PUB suppressor mounts and other HUB taper adapters.
