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.

    BCG

    Top of the line quality. I purchased a BCG from Fail Zero and the staking was so poor that the screws still backed out because they were staked while loose. You product is the best you can buy and the fast turnaround was appreciated.

    BCM Bolt Carrier

    Couldn't be happier... we'll unless it was free! After a bunch of research, determining what makes a bolt carrier good, better and best it was clear the BCM was the way to go! Pricing is more than fair and Bravo Co delivered a great product that I'm sure will offer YEARS or reliability!

    Amazing product, amazing company!

    Crazy fast shipping. Product just as described. Functions flawless perfect pinch on gas key. Uniform finish. Personally like the laser etch emblem. Proud to show off the name on quality parts in my builds. 99% of the time the dust cover is closed if you don't like the emblem.
