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.

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 and are backed by the Faxon Lifetime Guarantee. 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.
