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. Includes two interchangeable compact length of pull stock modules that provide comb height options for scope or iron sight use. By simply removing the rear sling swivel stud, stock modules can be changed in seconds. 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.
