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.

    If there were 1,000 stars to rate, I would

    When people put Love and Passion on their job, the results = high quality. Thats how BCM works. I was thinking which company go for my next build, Colt or BCM? We all know that Colt been there since Vietnam War and they are very experienced. But I noticed ... Colt is a great and experienced company but that doesn't mean that they are the best out there at this century. BCM has taken their products to a very high level in this present day. Who knows how is gonna be in the next years or centuries but, for now BCM is what Trust. Thak you BCM

    Order recieved inside of 72 hours. BCG headspaced properly and ran like a champ right out of the box.

    As far as BCG's go, this is in my opinion the best on the market. I don't think i'll be running any other makes in my rifles in the future.
