Ruger's American Rimfire rifle features a patent-pending Power Bedding integral bedding block system which positively locates the receiver and free-floats the barrel for outstanding accuracy. The cold hammer-forged barrel results in ultra-precise rifling which provides exceptional accuracy, longevity and easy cleaning. The American Rimfire rifle also has a Ruger Marksman Adjustable trigger, easy-to-use 10/22-style extended magazine release, and a 3/8" rimfire scope base that is machined into the receiver, which is also drilled and tapped. This Standard model has an 18" blued barrel, OD green synthetic stock with interchangeable standard length of pull, high comb stock module ideal for use with optics. A flush-mounted JMX-1 9-round rotary magazine included.
