LWRC ICA5 short stroke piston upper. 16.1" 5.56 1/7 twist. Maybe 300 rounds through it. Never had one issue with this. I ran it w a H buffer and a standard spring, add a Spring Co Blue Spring and she's really nice. Suppressed not suppressed doesnt matter. Ate everything thrown at her. 2 position adjustable gas block (suppressed/ not suppressed) . LWRC Extended Charging Handle. LWRC rail sections, LWRC AFG, LWRC sling mount. Will need a crush washer for the birdcage. 100 % Factory unit. W the box etc.
