As with all Faxon Barrels, the "Faxon Rimfire" line is made in-house at our Greater Cincinnati facility from raw bar stock and undergo the same rigorous testing and quality control measures that have made Faxon 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 either Salt Bath Nitride or PVD. We carry 10/22 threaded and non-threaded barrels with a variety of profiles including: straight fluted, pencil, flame fluted, bull barrel – flame fluted, and bull barrel – straight fluted. All Faxon 10/22 Barrels are backed by the Faxon Lifetime Guarantee.
