The Ruger American Gen II in 6mm ARC (brand part no. 46910) is CNC machined from stainless steel for smooth operation, with a familiar three-lug bolt and 70-degree throw that leaves plenty of clearance for a scope. Ruger finishes this rifle in Cobalt Cerakote and feeds it from an AR-style 10-round magazine, giving 6mm ARC shooters fast reloads with widely available AR-pattern magazines. A splatter-finished, adjustable synthetic stock provides secure grip without being abrasive, and an installed spacer lets a shooter fine-tune length of pull. The Ruger Marksman Adjustable trigger, spiral threaded barrel, and factory-installed radial port muzzle brake round out a rifle built for practical precision.
