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, fast delivery

    I bought a complete upper to go with my BCM lower. Fit perfectly, sights were dead on at 50yds right out of the box. Fit and finish of the rifle was outstanding. Ordering from the BCM website was easy, and I received the upper in 3 days. Lastly, I enjoyed the BCM goodies including a hat, stickers and posters.

    16" 300 complete upper

    Upper was just as I expected from BCM. I was impressed with how light it was and how much I liked the KMR handguard. Going to be an awesome gun, can't wait to go hunting with it this fall.

Solid fit to my Bushmaster Lower. Well balanced without extra weight. Easily my best & favorite to run

    16" 300 Blackout Upper

    Superior quality upper. I bought it for hunting applications knowing the caliber has more options than hunting. I have shot it with a Rugged Surge silencer and had tight groups with open sights at 30 yards. Going to put a low power scope on it. It is light weight but well built which makes it great for kids!
