Faxon Firearms is proud to partner with Q on the development of barrels for their revolutionary new round, 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, the Duty Series 8.6 Blackout 16in Big Gunner AR-10 Barrel is machined from raw bar stock in Faxon's greater Cincinnati Facility. This barrel is fully stress-relieved, air-gauge tested, Magnetic Particle Inspected, and 11-degree target crowned to ensure superior accuracy. Constructed of 4150 CMV, 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 and are backed by the Faxon Lifetime Guarantee.
