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.

    Awesome BCG PERIOD!!!

    I bought this BCG for a custom AR build the winter if 2012 just like every other reviewer on here the shipping and customer service from Bravo Co was superb. I shoot only black hills 75 grain match hollow points in this 18" 1/8 twist rifle and after 300 to 400 rounds I've never had a malfunction from this BCG. Keep making the good stuff Bravo Co. You have a customer for life with me!!!

    Bravo Co. BCG

    Bolt looks great after the reaserch I've poured over about bcg's and things you want to see verses not. Bravos' bcg has all the things you want in a high quality bolt at a very reasonable price. My bolt came just 2 days after I ordered. Great job Bravo.
