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.

    Down with the brown

    Same as the original but the coating is supposedly slicker and easier to clean. But it doesn’t matter how good it works if it doesn’t look cool. Peeing your pants is the coolest.

    Beautiful BCG

    Was tired of the regular Phosphate BCG’s and this added a beautiful flare on my fun gun. Works great as well and no complaints here.

    BCM FDE MPI BCG

    Lots of acronyms. This BCG is amazing. Not only does it look great, but it also performs fantastically. I have this bolt on my 11.5in BFH carbine upper with a CHF barrel. and it cycles great. For those who care, I have a JP Industries Silent Capture Spring with the H2 weight and the brass ejects at a perfect 3 O'clock. The recoil impulse is great as well. Side note, because my upper was 11.5in, the rubber O-ring was necessary for the ejector spring on the bolt carrier. If you do not install this O-ring (which is included with the bolt carrier upon purchase), you will have failure-to-eject and double-feed issues.
    Summary:
    - Great Looks
    - Great functionality
    - Tough
