10.5" 300 BLACKOUT Parkerized Heavy Barrel AR15 Upper Receiver with 10" Rail and A2 Flash Hider

The 300 AAC Blackout may be the best all-around AR15 cartridge. The 300 Blackout offers a wide range of projectile weights, can be run super- or sub-sonic, with or without a supressor, and it achieves full kinetic energy from a 9" barrel. Bottom line 300 BLK makes a great AR15 pistol or rifle, for personal defense or hunting. If you had to pick only one caliber, 300 Blackout would be a contender.

  • 10.5" 300 BLACKOUT 4150 Chrome Moly Parkerized Heavy Barrel with 1x8 Twist, 30 Cal Feed Ramp, and 5/8x24 Threads.
  • Mil-Spec Upper Receiver machined from 7075 T6 aluminum with forward assist and dust cover installed. Hard coat anodized MIL-STD 8625 Type 3 Class 2.

    10.5” 300 Blackout upper

    Just received this upper. Haven’t shot it yet but it looks beautiful. Looking forward to trying it out.

    Really nice quality upper that shoots very well...

    Actually purchased the 10.5" 1x7 upper - not the one listed here. Shipping was atrocious, but that's the fault of USPS - took 7 days for a Priority Mail pkg from up around Dalls, Tx to the Houston area. The upper arrived in good shape and fit up very well to the pistol lower I had built for it - very little play between upper and lower. Added my bcg and handle, checked headspace and took it out to shoot. Very tight groups at 50 yds and should only get better as the bore wears in a bit - really going to enjoy this combo !!!

    My favorite AR build

    I've officially put 20 rounds through it so far and zeroed my preferred red dot on it. It's without a doubt my favorite AR build so far!
