Faxon Firearms has partnered with Q to produce the 16" Big Gunner Carbine Length Barrel for the new 8.6 Blackout caliber. These barrels are machined from raw bar stock and are stress-relived, air-gauge tested, Magnetic Particle Inspected and 11-degree target crowned to provide exceptional accuracy. Employed with a 1:3 twist rate, these barrels are designed to channel the 8.6 BLK rotational energy providing increased energy on target. They are made from 4150 CMV steel with a salt bath nitride finish on the inside and outside for ultimate durability. Manufactured to high standards, the 16" 8.6 BLK Big Gunner Carbine Length Barrel goes through rigorous testing and is checked for headspace by custom hardened gauges to ensure performance and reliability. The 8.6 BLK Big Gunner barrels include thread protector and taper adapter.

Note: 8.6 BLK is not SAAMI certified, so please use appropriate caution when firing and using reloaded ammunition.
