Welcome To The Future

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, these 8.6 BLK barrels are machined from raw bar stock in our greater Cincinnati Facility. 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.

Consumer Note:
At the time of release, 8.6 BLK is not SAAMI certified. Please use appropriate caution while firing and when using reloaded ammunition.

    12” 8.6 Blk remake barrel

    Posted by Brian Blanchard on Jun 7th 2023

    I purchased this to replace a 308 barrel in a Remington 700CP pistol. The barrel is amazingly accurate. The first 9 shots (3 groups of 3 shots) as I sighted in the rifle result in three sub MOA groups at 100 yards using Gorilla 210gr TSX ammo. I was not expecting this type of performance from such a short barrel. I highly recommend the barrel.
