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.

Why pay more June 4, 2019
Reviewer: Shawn Campbell from Oklahoma City, OK United States  
I have purchased two of these uppers so far. They far exceeded my expectations. I would come back to these again for my next build every time. I don’t know why they are marked as blemished I don’t see any problems with the two I have. They will soon have far more scrapes and scratches as I use my firearms frequently. I also have the BCM bolt carrier groups and they are hands down top quality. Shop here you won’t regret anything.

BCM Bolt Carrier Group (MPI) - Auto June 4, 2019
Reviewer: Fred Price from El Paso, TX United States  
Have a 10.5 AR pistol build.  For some reason, I was having a FTE every 3 or 4 rounds.  I replaced the standard bcg with the auto, and now it runs perfectly.
