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.

Learn more about the round by Clicking Here.

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 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.

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.

We have noticed inconsistencies with 8.6 BLK ammunition available on the market. Ammunition that does not match cartridge print below cannot be guaranteed to function in our rifles or barrels.

    Extremely solid

    The quality on these barrels is off the charts, but be warned they are not light lol. I know the weight is listed but you really can’t picture how heavy these things are until you hold one. Really hoping this round takes off because I am impressed so far.

    Seems to be very well made, haven't gotten to fire it yet as I am waiting on reloading dies.
