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 Bolt carrier December 28, 2016
Reviewer: Frank Barile from Bel Air, MD United States  
The BCM Bolt Carrier Group is a quality piece of equipment as good as a Colt Bolt Carrier Group and maybe better. The reason, BCM actually has a better quality control process in my opinion and they really care about the BCM brand. I have two complete BCM guns and all I can say is... reliably perfect!
