The Ruger American Gen II .22 ARC Bolt-Action Rifle with 20-Inch Spiral-Fluted Threaded Barrel and Muzzle Brake (brand part no. 46918) is a bolt-action centerfire rifle from Ruger chambered in .22 ARC. Its 20-inch spiral-fluted barrel is threaded 1/2-28 and carries a factory-installed radial port muzzle brake, so the rifle arrives ready for a scope and the muzzle hardware is already handled. A 10-round AR-style magazine feeds the action, and a one-piece Picatinny scope base is installed on the receiver in place of iron sights. The Gen II American stock, three-position tang safety and Marksman Adjustable trigger round out a rifle aimed at hunters and range shooters who want a modern .22 ARC bolt gun.
