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 quality and customer service.

    I opted not to order the BCM BCG when I initially purchased my ar15 upper. After deciding to go ahead and add it to my order, my upper was already shipped. Bravo Company still honored my previous order and charge me the same price had I ordered it together. A substantial savings to me. Thank you Bravo Company

    Satisfied

    I placed my order on a Friday afternoon and received it early the following Monday. Upon inspection, I can say I am extremely satisfied with the quality of this product. I have purchased many parts from BCM and plan to continue to do so in the future. Although I have not tested this BCG yet, due to build in process, I will update review once I order the BCM barrel to complete build!
