Bravo Company Manufacturing is now offering a line of 300 Blackout upper carbines and upper receiver groups in Recce 16″, 12.5″ CQB, and 10″ pistol configurations and lengths. One of the greatest benefits of 300 Blackout ARs is that they utilize virtually all of the same parts and components as an equivalent 5.56 AR, allowing shooters to use the same magazines and accessories between rifles chambered for either caliber. This modularity extends towards BCM’s 300 Blackout uppers, which come standard with the KMR-Alpha forend.


BCM’s 300 Blackout line is built on their 1:7 twist 11595E Certified Steel Barrels. Both the bore and chamber are chrome-lined, and each barrel features a continuous taper profile “designed to optimize balance, performance and weight”. Additionally, BCM barrels lack the sharp handguard cap shoulder common on AR-platform barrels, the removal of which is designed to improve barrel harmonics and accuracy. The 300 Blackout line also includes the BCM Comp Mod 1 – 762/300 BLK.


BCM Gunfighters Travis Haley and Tom Spooner has this to say about 300 Blackout:

My main requirements in a combat round are versatility and recoil control. In testing 300 Blackout over the years, I have found it performs from CQB range out to, and exceeding, 500 meters. Despite having a slightly more potent impulse, the recoil is still manageable, which means a shooter can engage threats quickly and, given the increased mass, more efficiently.

The ability to have the power of a .30 caliber round, with minimally increased recoil over a 5.56×45 round in a sub 10 inch platform is ideal for most soldiers in Direct Action units. As fielded, in an AR pattern carbine, the operator is already familiar with the operating system and ergonomics of the weapon.

    i still remember a buddy of mine telling me that the 300 blackout would never catch on and it would be a cult cartridge …. LOL

    I saw a 9″ BCM 300BLK reach out, suppressed and unsuppressed, 100M with an unmagnified T1 and put a rather small fist-sized hole in an IPSEC target. I’m a believer.

    • BillC says:

      You mean it put a .30 cal sized hole on a IPSC target, and 100 meters is pretty much, no big-whoop.

    • Thomas says:

      You don’t need a long barrel to max velocities from 300BLK. Long barrels don’t contribute to accuracy. My 300 WSM easily gets 3000+ FPS from a 17 inch barrel.

      I love BCM. The only rifle I will take over a Colt rifle.

      • mike says:

        Ten rounds in 30 seconds in a hole the size of a baby’s fist is pretty good unmagnified at 100M from where I’m sitting, but I forgot I’m not a fraction the sharpshooter the keyboard commandos are. Aw shucks.

    Best day ever!!!

    Sure would like to see uppers for sale without the hand guards.

    • Bradkaf308 says:

      Agreed. Canadian distributor? Nice kit. 9 or 12, 9 or 12 hmmm?

      • 404953C says:

        Bradkaf308 – Haley Strategic is an international distributor for BCM. They don’t do individual sales, but if your FFL reaches out…

        • Bradkaf308 says:

          Thanks 404953C. I know someone with a store and I’ll get him to enquire. But now that you mention HSP, Rampart International is the CDN rep for HSP. I’ll ask them also.

    Too bad the ammo is still not plentiful and the cost is easily double that of 5.56 today.

    • james says:

      Tons on the shelf here, a year ago not so much. Mostly supersonic with premium bullets though. Maybe it’s starting to get there.

      • Larry says:

        It is better sure. However if I go to say sgammo.com and look at options for both I see 3 times as much for 5.56 and the price for 5.56 is half as much or less.

        I would love to see 300 blackout replace 5.56 but I wont make the move until the cost comes down some and I can walk into a back water walmart and pickup some.

  6. Brad says:

    Anyone know if an AAC SDN 6 would fit on these? I know the barrel is 9″ but I see the rail is actuall 8.39″. With the threads at .62″ that doesn’t leave any room to spare. Although I may not be doing the math correctly on this?
