16" 8.6 Blackout AR-10 Upper Assembly | Kaw Valley ASR Break | 1x3 CMV Carbine Length HBAR Barrel | 15" MLOK Rail
The 8.6 Blackout isn't just another caliber; it’s a purpose-built solution for the AR-10 platform that rivals the energy of the .338 Lapua in a much more compact footprint. This system thrives with a fast 1:3 twist rate, specifically tuned for subsonic 300gr to 350gr loads to provide unrivaled rotational energy and expansion upon impact. If you're building a dedicated suppressed hunting rifle or a short-barreled tactical rig, an 8.6 Blackout upper assembly offers the massive stopping power and whisper-quiet performance required to push the limits of the large-frame gas gun.
Ballistic Barn uppers are American Made and machined by manufacturers of mil-spec AR-15 components. All barrels are individually checked for headspace using Manson go and no-go gauges.

8.6 upper
Great looking well built upper and it arrived way faster than expected. Kaw Valley break is awsome and my suppressor fit on it without issue. Shoots very accurate. 1 inch groups so far but will try to dial it in more if I can.

8.6 Blackout
Very well made upper and well packed for shipping. Fit on my PSA lower and did a function check that checks out but have not fired. Still waiting on ammo.
