    Very nice looking BCG, (If that matters) Seems to be of solid quality. Comes with everything, Bolt, Crane 'O' ring (black) and insert, Firing pin, Cam pin, kotter pin. M-16/Auto pattern. Quality Gas Key staking...Can't find anything negative to say about it so.... 5 stars.
    The Nitride is DEFINITELY worth the extra $4. Beautiful finish!
