Faxon Firearms is proud to partner with Q on the development of barrels for their revolutionary round, the 8.6 Blackout (8.6 BLK). With barrels employing an impressive 1:3 twist rate, 8.6 BLK channels rotational energy to increase energy on-target. As with all Faxon Barrels, these 8.6 BLK barrels are machined from raw bar stock. Faxon 8.6 BLK barrels are fully stress-relieved, air-gauge tested, Magnetic Particle Inspected, and 11-degree target crowned to ensure superior accuracy. Constructed of 416-R Stainless Steel, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All Faxon Barrels are individually checked for headspace by precision custom hardened gauges. Faxon RemAge Style Barrels for 8.6 BLK ship with a Thread Protector, Taper Adapter, and Faxon RemAge Style Barrel Nut. Faxon's barrel nut uses a standard AR Armorer's Castlenut Wrench profile.
