Faxon Firearms Rimfire Barrel Features The Faxon Firearms Rimfire barrel brings the same manufacturing process used on Faxon s AR and pistol barrels down to the .22 LR platform machined from raw 416R stainless steel bar stock at their Cincinnati facility. Six groove rifling cut at a 1:16 twist stabilizes standard and subsonic .22 LR loads while the recessed target crown protects the rifling from dings during handling and storage. Every barrel is Magnetic Particle Inspected before it leaves the factory a quality control step most rimfire barrels in this price range skip entirely. The result is a barrel built to the same tolerances as Faxon s centerfire lineup just scaled down for the 10/22. The straight fluted profile cuts weight relative to a stock 10/22 barrel without sacrificing the rigidity that keeps groups tight making the rifle quicker to swing on plinking and small game targets. A Salt Bath nitride finish coats the barrel for corrosion resistance and easy cleaning after a day at the range. The 1/2x28 thread pitch on the muzzle accepts standard .22 caliber suppressors and compensators a popular addition for rimfire shooters chasing reduced report and recoil. Direct fit to the Ruger 10/22 action means installation is a straightforward drop in upgrade for anyone looking to modernize their rifle.
