The 100% American-made Ruger American Rimfire bolt-action rifle builds on the enormous success of the centerfire Ruger American Rifle. With many of the standard Ruger American Rifle features, this new line also combines several design innovations from the popular 10/22 rimfire rifle. Each Ruger American Rimfire Rifle includes two, interchangeable stock modules that provide comb height options for scope or iron sight use. Ruger's patent-pending Power Bedding integral bedding block system positively locates the receiver and free-floats the barrel for outstanding accuracy. The cold hammer-forged barrel results in ultra-precise rifling that provides exceptional accuracy and longevity and easy cleaning. The ergonomic, lightweight black synthetic stock blends a classic look with modern forend contouring and grip serrations. A 60° bolt provides ample scope clearance and the easy-to-use, receiver-mounted bolt release allows the bolt to be readily removed without requiring a pull of the trigger, a unique safety feature among rimfire, bolt-action rifles. This variant has a threaded barrel for suppressor attachment.
