Building an 8.6 Blackout AR
Caleb from Brownells walks through building a large frame AR-10 upper receiver chambered in 8.6 Blackout. Often described as the AR-10’s version of 300 Blackout, the 8.6 Blackout is designed for subsonic shooting and excels when suppressed. In this video, Caleb explains the cartridge, details the parts selection including Aero Precision receivers, Faxon barrel, Midwest Industries handguard, Dead Air suppressor setup, and Strike Industries Arca rail, then assembles the upper step by step.
