As with all Faxon Barrels, these 8.6 BLK barrels are machined from raw bar stock in their 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.
