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.

    These are superior quality BCG.
    Worth every penny.
    Bought 3 already. Just hope the giveaways are more consistent. It seems like my giveaways decrease everytime I order. Bit bitter about it
    Nonetheless......BCM BCG is the only I will buy......

    Best bolt carrier in the industry!

    After many bolts used from a professional standpoint I think BCM takes the cake. I’ve used many of the trusted brands on the market and can finally say after thousands of rounds down range this bolt for my money is in my opinion the best. I would put this bolt in my rifle and take it to hell and back without thinking twice. Thank you BCM for the awesome bombproof products and Semper Fi Paul!!
