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.

    300 Blackout Complete Upper

    Terrific quality and quick shipping with BCM swag. This is why BCM uppers have homes on 3 of my rifles so far. Terrific company.

    Solid company

    I've been wanting a BCM upper for a while after many word of mouth recommendations. Just waiting on my stock for my build to be complete, so I haven't run it yet. Fit and finish are excellent! Had to take off that beautiful comp mod 1(no A2 birdcage here!) to fit my can, but I'll use it somewhere! Slim handguards even with rail covers installed. And thanks guys for all the BCM swag! It was like Christmas all over again. Semper Fi brothers.

    9" 300BLK

    This is nothing short of amazing! Haven't found anything yet that shoots larger than an inch out of it. If you're hesitating about getting one; stop and add it to your cart!

    Perfect upper on sbr host

    as mentioned about its a quality and reasonably priced 300blk upper...
    but not everything is perfect.. I feel that revisions to the rail must be made. Everyone is gonna say but you bought the rail closest to the muzzle.. yes I did but I have other uppers and I have never had this much 1st world problems mounting a flash hider/muzzle brake.
    Word of the wise I hope you have a thin line type wrench, crowfoot, etc. to be able to torque your preferred muzzle device onto this upper.
    Shoots like a champ to close this out. 9in 200gr/220gr ammo with Spikes st-t2 buffer, and BCM BCG. No failures and brass land in the same spot all day long.

    BCM 9" 300 BO Upper - Very Happy!

    Recently received my BCM upper. I am a DD guy and I put this on my DD MK18 lower. I wanted to both lighten the SBR as well as try out 300 BO in a package short enough with a folding stock to fit in a backpack.

    I love this upper. Completely sold on it - you can really feel the quality. Also I was very impressed with the amount of swag (hat, posters, stickers, magazines, etc.) that were included with the upper purchase. I did not get all that from DD. I will exploring additional BCM rifle purchases in the future.

    Little nasty

    9" 300blk out upper. Of course it's a little nasty coming from Bravo Company. Couldn't ask for better.

    Excellent product, reconsider packaging

    Awesome Upper. Shipped and received quickly. Box was packed full of swag - bonus. Consider eliminating the exact product description on the outside of the box. It lets every delivery driver and person who sees the box on your porch know exactly what is in the box. People stealing from the porch is too common.

    Awesom product

    Some of the Finest made uppers Ive ever seen. Love this product and company. For a short barrel it is extremely accurate and very little recoil. Impressed with everything about it! Paired perfectly with the Black Rain Ordinance and CMMG lower parts kit. The extra posters and stickers were icing on the cake! Well done BRAVO Company!!
