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, tang safety, 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. Included is Williams' fiber optic front sight and adjustable, "V" slot, folding-leaf rear and sling swivel studs. This Standard model has a 22" blued barrel, black synthetic stock with two long length of pull modules, and a detachable, flush-mounted 10/22 BX-1 10-round rotary magazine .
