dropped it on a custom upper with an LMT BCG, ran 200 rounds of M193 and 50 of 77gr SMK. groups were sub MOA with the 77s off a bag. carbine length gas was a little snappy but the chamber finish is mirror polished. headspace checked perfect with my Forster gauges
Wilson Combat 11.3 inch 5.56 carbine length stainless barrel had correct headspace out of the box. Carbine gas at 11.3 is hot but cycles consistently. Stainless finish handles suppressed shooting heat. Solid SBR barrel from a premium maker.
