BCM® has taken great care to ensure the best possible performance and interchangeability. However, due to the large operational range of 300 Blackout ammunition in the market place, BCM® cannot guarantee function will all ammunition types in all conditions. These barrels were designed to run with a H3 buffer with high velocity ammo. If running subsonic ammunition, it is recommended to run your suppressor and a carbine buffer. Fine tuning may be required in limited instances based on ammo and buffer choices that work best for the desired application. BCM® also recommends running the Crane O-ring (provided with all BCM® Bolt Carrier Groups) over the extractor with 300 Blackout.

    Product looks and functions great.

    Only part I would change is choosing of a muzzle device. Don't remember there being a good description of what the devices are designed to do. Kinda leave ya guessing on what ur getting.

    Wow

    I have been looking for a .300 BLK. upper for several months . I done the reading , asked the forums and reviewed the top tube video.
    Went with the BCM and can't be happier!. First at the unboxing the fit and feel is fantastic. A totally solid and well made piece of iron.
    For range placed on a SBR lower and ran flawlessly with 220 grain subs. Switched out the muzzle brake which worked great, so it would accept my Surefire 300 SPS can also switched to a H2 buffer and continued to run with the 220 gain subs . And ran without a hiccup . My Mk 18 is going back into the safe. This has become the truck gun and my go to rifle. Thank you BCM for a rifle I can be proud of and depend on without question.

    Fantastic upper

    Upper performs flawlessly. I love how light weight it is. The M-LOK rail is great; it is nice and slim and therefore easy to grip, and saves weight because you only attach rail sections where you need them.

    Impeccable Service, swag and more!

    Online shopping is easy, BCM makes us even better! Simple navigation on the website. Order was placed on a Sunday, was enough by Tuesday and delivered Saturday all standard service level and almost unbelievable! Then loaded with swag, BCM print magazine, posters, stickers and a BCM Hat that was immediately my daily wear! 100% would order again and suggest anyone in the market do the same. You can’t beat the service and the hardware speaks for itself and is next level as well!
