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 product

    Not that my words will make any difference, since Bravo Company's reputation precedes them.

    Goes where it goes and does what it does.

    Top Notch Gear and Service

    Put this in a 10.5" pistol build using the BCM H2 buffer as well. Smoothest operating gun I own. If you want something you can trust your like with, this BCG is that item.

    BCM BCG

    There is a reason EVERYONE compairs their BCGs against BCM. BCM sets the benchmark. If you want rock solid performance, get a BCM.

    Top Notch bcg

    I bought this bcg recently to replace a sub par one that came with my rifle. If you are looking for a full auto bcg with proper staking and 1st class qc then look no further!!!

    Bolt carrier group

    Matched this bolt carrier group up with your BMC standard 20 inch government profile upper receiver group. The bolt carrier group was dirty when I received but that is normal. Shot two rounds with out any problems.

    Fired perfectly

    Used this to replace another BCG. Fired first time without issue and every time since. There is a reason everyone trusts BCM.
