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.

    Great Product!

    BCM has done their homework with this upper. Properly gassed and when used with their recommended buffer, ejection pattern is excellent. I've heard of feed issues with supersonic ammo and pistol gas system. Tested with 110gr ammo, the only feed issues were magazine related (rounds are short and move around in magazine, use mags with stout springs to prevent ammo movement), no problems at all with upper. Again, flawless operation, great product!

    300 BLK 9 in upper.

    It was a quick delivery, and it showed up in good shape. It was for a coworker, who traded me a mountain bike for the upper. We work at Park City Gun Club and we have a customer who has the same upper. We've shot it a bit and we both love it and will continue to buy your products. Also the gunfighter charging handle kicks ass. That's all I have to say about that.

    9" 300 Blk Upper

    Great fit and finish. This upper has cycled about 500 rounds of both subs and supers reliably so far. The KMR-Alpha rail is one of the nicest rails I've had on any gun, it just fits your hand right. If you are looking for a great upper at a great price, you won't go wrong with BCM.

    Satisfied customer

    I finally get to the range today and I am extremely pleased with my upper. Using the buffers you advise and Remington factory ammo I had flawless function with supers, subs, and subs with a 9mm Raptor can. I can't wait for my Hybrid can so I can shoot supers suppressed. Thank you for an excellent product at a fair price.
