The Ruger American Gen II Rifle in .22 ARC with a 20-inch threaded barrel (Ruger part no. 46918) brings Ruger’s second-generation American platform to a fast-growing, high-velocity cartridge built for long-range varmint and predator hunting. Ruger cold hammer-forges the 20-inch barrel and adds spiral fluting to shave weight while a factory-installed radial port muzzle brake tames recoil and manages muzzle rise. The user-adjustable Ruger Marksman Adjustable trigger and Power Bedding integral bedding system work together to deliver consistent, repeatable accuracy shot after shot. A stainless one-piece bolt with a 70-degree throw and an oversized bolt handle keep cycling smooth even with a magnified optic mounted on the factory Picatinny rail, and the splatter-finished, adjustable stock lets hunters dial in their fit in the field.
