Stripped carrier is finished in an Ion Bonded Flat Dark Earth. Lowers friction and cleans easier, however the carrier still needs a thin coat of oil on it at all times.

BCM® (MPI) complete bolt carrier group is fully assembled. (BCG)

Bolt carrier group (auto version) for your AR15, M16, or M4. Parkerized exterior and chrome lined inside carrier. Machined to USGI specifications. This M16/M4 carrier includes the proper Mil-Spec gas key. Gas key is chrome lined and heat treated per GI specifications. Gas key is secured to carrier via USGI domestic mfg Grade 8 fasteners and properly staked per Mil-Specs. These properly hardened parts ensure a strong staking and proper gas system functioning.

The bolt assembly is machined from the correct Mil-Spec Carpenter No. 158 steel, shot peened for increased strength, includes tool steel machined extractor and ejector, BCM Extractor Spring, and is HPT (High Pressure Tested) and MPI (Magnetic Particle Inspected).

Prior to shipping, all BCM Bolt Carrier Groups are test fired for function. As such, the Bolt Carrier Group will show handling marks consistent with these quality control procedures.

    The BCM bolt carrier group is one of the best you can get out there today. That is why they are always in demand. You can never go wrong with these and they are great to trade with as well.

    Love the quality and it runs smooth in my new Aero precision build. Always buy Bravo company products. Top notch.

    My last six AR builds have all had BCM BCGs, but in standard black. I happend to be on the website when the FDE models got restocked and jumped on it. Same quality, awesome as usual, just a little different. It's good to change things up sometimes.

    Initially purchased to swap with a nickel boron BCG in a .300 Blackout to compliment the FDE furniture, and to utilize the one I’m swapping with as a spare BCG. The BCM BCG arrived within just a few days from purchasing and although not been run yet, it screams quality.

    I had to buy this from brownells because they were out of stock here but their bcg is very nice, smooth and there’s something to be said about a company that puts their logo on their product. Not to mention the fde looks awesome. Why wouldn’t you pay the extra $10 for it!!?? It also shipped with a little rubber o-ring for the extractor which was easily installed.
