Faxon Firearms 8.6 Black Rifle Barrel 12inch Medium Profile 1-3 Twist Black Nitride. These barrels are compatible with Savage 110 and Savage Small Shank Receivers. 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. PLEASE NOTE: 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. Using cartridges made specifically for semi-auto rifles may cause light primer strikes in bolt action rifles due to hard primers.
