Faxon Firearms 12B216N16FMQT: The .22 LR has been a perennial favorite for beginning and seasoned shooters alike. The \"Faxon Rimfire\" line is made in-house at the Cincinnati facility from raw bar stock, and undergo the same rigorous testing and quality control measures that have made the AR and pistol barrels a market favorite. These barrels are made from 416-R stainless steel, given 6 Groove Rifling at a 1:16 twist, and a Recessed Target Crown. Barrels are Magnetic Particle Inspected, and are finished in Salt Bath Nitride. To give these Faxon Rimfire barrels the unique touch, we have adapted 3 of the most popular barrel profiles from the AR platform to rimfire: Pencil, Straight Fluted, and the patented Flame Fluted profile. Faxon Rimfire barrels offer weight-savings to typical factory barrels for 10/22.
