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.

    BMC BCG

    Quality product, my choice for first 5.57 pistol build. Rounds down range, bcg performed without malfunction with BMC carbine gas tube, LMT 10.5 barrel w/fsb, and BMC H buffer spring/BMC standard carbine buffer spring.

    SemperFi,

    Great product

    The BCM BCG is definitely one of the best out there, and is the standard I use to inspect other BCG. I made the mistake of getting a FailZero for my 11.5, swapped it out for a BCM and it is so much smoother. And with how well this company gasses their uppers and guns, they run super smooth, especially with the BCM BCG.
