Faxon believes that firearms bring people together and create generational memories. Since the 19th century, the .22 LR has been a perennial favorite for beginning and seasoned shooters alike. Thats why theyre excited to bring you everything you love about their AR and pistol barrels to the beloved 22LR. As with all Faxon Barrels, the Faxon Rimfire line is made in-house at their Cincinnati facility from raw bar stock, and undergo the same rigorous testing and quality control measures that have made their 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. Faxon Rimfire barrels offer weight-savings to typical factory barrels for 10/22.Features :Barrel Caliber: .22 LRBarrel Chamber: .22 LR SportingBarrel Profile: PencilBarrel Material: 416-R StainlessBarrel Weight: 1.0 lbs,Barrel Length: 16";"Barrel Twist: 1:16"Barrel Finish: Salt Bath NitrideRifling: 6 GrooveTarget Crown: Recessed
