Written by Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE), Chief of the Firearms Technology Branch
...M16 bolt carriers are not designed and intended solely and exclusively for use in converting a weapon into a machinegun and are not any combination of parts from which a machinegun can be assembled. Further, an M16 bolt carrier is not a firearm as defined in the GCA or a machinegun as defined in the NFA. An M16 bolt carrier is simply a machinegun part and as such its domestic sale and possession is unregulated under the Federal firearms laws. It is not unlawful to utilize a M16 machinegun bolt carrier in a semiautomatic AR15 type rifle.

    Excellent BCG!

    Since I already own a BCM Recce, I already knew I'd be running a BCM bcg in my 300blk pistol build. After a quick strip and lube, I took off to the range. I fully expected the pistol to run flawless and I was not disappointed. I am completely satisfied and continue to recommend BCM products.

    Excellent Upgrade for Reliability

    Purchased this 2 years ago to help resolve spotty reliability in my carbine, and since then I have had zero malfunctions. Even after a few thousand rounds, there are few wear marks, and with sufficient lubrication, I don't see this needing replacement anytime soon. Thank you Bravo Company for a great product that's worth every penny!

    Bolt Carrier

    This is the best bolt carrier group on the market. The quality and control at BCM is second to none.
    I have 4 BCM REECE rifles and could not be happier.
    When I get into my patrol car I never worry about my rifle failing me

    Perfect

    Excellent quality BCG as good as my Colt BCG. For the money BCM is the best there is. Shipping was very fast it took only 3 days by mail and was shipped within only an hour after my order was placed. BCM has the best customer service and fastest shipping out there. I'm sure this BCG will last through many thousands of rounds. Mil-spec quality.
