...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.

    Yowza! Great service

    Was fast, efficient and I will def shop here again. I'd also like to note that I made 8 purchases for my AR build all on the same day and this was the first and only piece to show up so far. Way faster than all the other companies I have dealt with so far! Also. I loved all the free stickers. Nice touch. They're on my truck, computer and hydro flask as we speak. I will rock BCM till I die!

    Impeccable, Very Nice

    Everything I'd expect, should provide years of great service. Came with optional extractor spring o-ring if more forceful shell extraction is necessary.

    Excellent BCG

    Bravo BCG's do not have a great reputation for no reason. Very well made and ships with a generous amount of oil.

    Great products all around. Bravo Bravo!

    BCM BCG nice packaging!

    Just received a new in the bag BCM bolt carrier group. The BCG was well lubed and sealed in a poly bag, with BCM O-ring sealed in another section of the bag.

    Excellent choice for a Bolt Carrier!

    I needed a Bolt Carrier for a build that I was completing and while I didn't need the bolt (had one headspaced to the barrel already) - I'm glad I have another Excellent quality spare bolt.

    First off - the packaging. BCM ships their Complete Bolt Carrier Group in a sealed, heavy plastic bag filled with lube. Then they bubble wrap the entire Carrier Group to ensure it arrives undamaged.

    Inspected Carrier Group and it was flawless. Staked perfectly - honestly, one of the best staking jobs I've ever seen.

    Have over 1,000 flawless rounds through it in less than a month and will only be buying BCM from here on out. Quality for what you get is amazing. Buy with confidence that you will be getting the best.
