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.

    Awesome

    Functions flawlessly with all types of ammo. Just follow buffer instructions for subsonic and supersonic. Excellent service and glassy shopping. The highest quality parts always. Thanks.

    Great Accuracy for such a short barrel.

    Great accuracy I’m very happy with this upper. 220 g Remington seem to work the best with an H buffer. Tried 208 g Hornady BLACK had a lot of mis feeds tried an standard buffer seemed worse might need an H2 for that ammo. Will probably just use the Remington since never had one jam or mis feed round after round ran like a Swiss watch also saw better accuracy with the Remington.

    BCM Customer for Life

    The fit and function of this upper are excellent. After approximately 700 rounds shooting subs and supers I have had zero malfunctions.

    I have never dealt with a company producing such a high quality product with such excellent customer service. BCM is a model for American business, and I am proud to use their rifles to protect my family and for their products to be a manifestation of the freedoms we enjoy in this country.

    Excellent upper

    I would argue BCM makes the best factory blackout upper you can buy. It has run well is everything from 110-220gr. Reliable and pretty accurate, getting about 2.5" groups at 100 Meters with 110 barnes.
    My only complaint is all the white writing. So sick of all my stuff looking like a billboard. I have 5 BCM uppers, they are all excellent, but the advertising on them is a little much. Between the BCG and upper there is just so much white BCM in your face. Surprised their new stock doesn't have a big BCM in white printed on both sides of it.

    Icing on the cake of my first 80% lower AR pistol

    AMT 80% lower, JP enterprises gen 2 silent buffer spring, ALG defense ACTrigger, 5DTactical jig, surefire mini can over surefire compensator. Tight groups 50,100, and 200 with sub and supersonic without waking up the neighbors. BCM is the standout on fit and finish. Thanks for the excellence.

    Great Experience

    Prompt service (the credit card / shipping requirements suck) and Bravo Company threw in lots of free swag! I will certainly purchase again from Bravo Company!

    Too bad the BATF does not move as quickly, as I will not be able to use the upper for probably 6 mos.
