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.

    Unbelievable Upper

    The quality of this upper is phenomenal. It is very sturdy, quite lightweight for being an upper, and the barrel is incredibly accurate with its 1:7 twist. I bought this for my build in 300blk, and it performs exceptionally well. I am beyond pleased with this purchase. With BCM, you definitely get what you pay for-- and it's worth it. This will last you a lifetime. Take care of it, and it will take care of you.

    Love this upper

    This upper is light as a feather but built like a tank. Absolutely love the look and feel of the KMR Alpha handguard too. I run it suppressed (Surefire 300 SPS) with subsonic ammo and have never had a malfunction. I use the Geissele super42 braided buffer spring and (H1 buffer). This pistol runs really smooth with very little recoil and is probably one of the quietest guns I own. Everyone should have one of these....Love the swag BCM always throws in too.

    Great product, well built, and runs great

    This is my first 300 Blackout, and I love it. This is without question a quality product.

    Shipping was fast and arrived with lots of promo items (stickers, catalogs, hat, etc). I do recommend BCM, and will buy from them in the future.

    Great Product

    I bought this product about a year and a half ago. I thoroughly enjoy this upper. I have been running it suppressed with my bcm pistol lower haven't had any issues since I swapped to the right buffer for subs, as always great swag that came with it.

    Love It

    Used this as an extra upper for my 300 blackout. My other upper has an infrared scope so I put an eotech with magnifier on the BCM. It is lights out accurate. Carry it with me when turkey hunting since I see more wild hogs than turkey.

    Excellent product, service, and SWAG

    The upper I ordered was very well put together. I've worked with a lot of ARs and I can recognize the quality of the product. Shipped and arrived very quickly. LOTS of great swag...posters, stickers, and a hat. Good advertising on their part and it was a great extra for me! I highly recommend BCM.

    Absolutely Beautiful

    My first purchase from Bravo Company. I was building a subsonic .300 Blackout pistol with an 80 percent lower. I wanted the 7-in handguard so the end would not be too close to the suppressor for my Shrek fingers. I went with a full-build upper. The BCM upper was quality through and through. Easy ordering, fast delivery, well packaged. Perfect barrel length and pitch for my ammo. Workmanship and fit was superb. Functions flawlessly. I will have no qualms about ordering from Bravo Company again.
