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.

    Top Notch

    Ordered, and in less than a week it was on my door step. I expected nothing less, and was not let down.

    Excellent!

    I can't even begin to describe how impressed I am with this purchase. Extremely easy process and lightning fast shipping. I was originally considering going with a cheaper alternative to BCM for my build, but after receiving the upper, I couldn't be happier, and I'll definitely support BCM for life.

    More Good Stuff from BCM

    I have pretty high expectations for the stuff that BCM makes and sells through its website. My EAG Tactical Carbine is the standard for reliability I use to judge everything else. I believe that the Paul and the BCM gang would not offer a product if it wasn't fully tested and approved by them.
    So I had pretty high expectations for their 300 Blk offering. I waited to buy into the 300 Blk craze until BCM got behind it and offered what I wanted; a 9" 300 Blk upper to go on my NFA BCM lower. In summary;
    Its light. It functioned 100% and put the brass in a neat little pile to my right rear. Its as accurate as it needs to be. The chronograph said it got better velocity than expected. I couldn't ask for anything more. Totally satisfied.

    300 Blk Done Right.

    I purchased the 9 inch BCM 300 blk upper with high expectations, and was not disappointed. Overall fit and finish was above average, and it fit my Colt SBR lower like a glove with no play.

    After a few hundred rounds of 120 grain factory Remington, and handloaded Barnes 110 grain, the upper has proved both accurate and reliable. It is also very well balaced.

    Once my paperwork gets in, I will be attaching a Surefire 300SPS to the end of this beauty, to see how she does suppressed. This is not much of a review, with only a few hundred round in supersonic, but i have a feeling it will continue to bring smiles, much like the 5.56 BCM upper I own with upwards of 20k rounds. Great job BCM.
