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.

    BCM MPI Auto BCG

    Won't use ANY other BCG in our shop Builds. BCM is American Quality UNEQUALED in Reliability and Dependability. When ones Life depends on THE BEST, BCM meets the challenge EVERY TIME!

    I won't buy anything else

    Tens of thousands of rounds through black rifles with this BCG and never a failure due to the bolt carrier group. I'm tempted by cheaper BCGs, but just can't bring myself to even try them. Bravo Company's BCG is bullet proof and worth every last penny.

    The best BCG bar none!

    I purchased my BCM Bolt Carrier Group before the prices went up in 2012 and I 'm just now getting around to writing a review. After using this product for a while I now wish I had bought two more of them. I know, hind sight is 20/20.

    Out of the three different BCG I own, (DPMS, Colt and BCM), the quality, functionality and ease of cleaning of this Bravo Company product is absolutely outstanding. I have over 800 rounds through my carbine using this particular BCG with all types of ammo, clean ammo, dirty ammo, reloads and commercial ammo and the BCM has worked flawlessly wet or dry.

    Cudo's to your group of fine craftsmen and women, keep up the great work. I look forward to doing business with you in the future.

    Best bolt carrier group on the market. PERIOD. I don't care if its for a "fun" gun, a duty weapon, or home defense rig, this is what you NEED to get the job done.
