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 upper

    Matted this to my Mega SBR lower and it makes a great rifle. I tried 300blk a few years ago and the upper left a bad taste in my mouth (lots of chambering issues). When BCM entered the market I had to give it a try again. I have only about 500rds through it but it has run perfect. With an aimpoint The accuracy is very good for a SBR.

    Outstanding

    You get what you pay for. I originally bought a cheep 300 AAC pistol upper from a discount web site, and what do know, I had major problems with it and had to return it. This one is the complete opposite. It works and looks flawless. Shoots 1" groups at 50 yards, I couldn't be happier. If your interested it a 300 pistol definitely get this one. You will forget about the few extra bucks you paid but you'll always know your gun sucks if you buy a discount POS. Plus I consider this one to be a good value for the high quality your getting.

    Completely satisfied!

    I've been using BCM products for years so when I decided to get into 300 blackout they were the obvious choice for me. As always you can see the quality as soon as it arrives....which was quick thanks the great crew at BCM. But obviously how it performs is what really matters and there's no disappointment there. I've used it with and without a SilencerCo Omega with 110gr to 220 grain rounds and haven't had a single malfunction. For the time being I've been limited to a 100yd range and I've been very pleased with the accuracy. The BCM KMR rail system is very light and extremely comfortable, I'd happily switch out my quad rail equipped AR's for these. Like the title says I'm completely satisfied since BCM delivered nothing less than I've become accustomed to from them.

    Perfect

    This was the perfect upper for my SBR blackout build running a suppressor. Everything is built just right and works how it should. What else can I ask for?

    9" 300 blk

    Lightweight, well constructed, it is a great upper. The Keymod rail is strong but light. Ate up supers and subs with no issues. Good groups with factory ammo.
    Plus fast shipping, can'take go wrong with BCM.
