    Great KeyMod attachment

    Bought this rail section to throw on my AR in case I can't find specific KeyMod accessories that I like. Haven't had to use it, but quality item as you would expect from BCM.

    perfect

    The local shops were out of the 4" rail I needed. Bravo Company, of course, had the exact item in stock. Three days later it was mounted to my new rail. Fit was perfect to the rail and it works great with my bi-pod.
    BCM has the gear.

    BCM 20" 410 SS Alpha Keymod

    Outstanding build quality. Smooth barrel with no visible tool markings and absent of any scratches. Keymod to barrel fitment was dead center. Keymod to upper receiver picatinny rail fitment had no gaps at all. No wiggle in any parts. Feels like a brick in the hands, stout and sturdy. Shot 15 rounds of XM193 through the same ragged hole. Very pleased with the price to value.
