(Weaver style bases supplied) Redfield Revolution riflescope available for all centerfire models }} The Ruger American Rifle is a family of budget-level hunting/sporting bolt action centerfire rifle made by Sturm, Ruger & Co., who also produces a line of rimfire rifles with similar designs called the Ruger American Rimfire. DesignThe Ruger American has a receiver made from 4140 chrome-moly bar stock and a hammer-forged barrel with a blued black oxide finish, mounted onto a black polymer composite stock. Some models are also available in a stainless steel variant. Rather than using a traditional recoil lug, the rifle's barreled action is secured in the stock by a bedding system known as "Power Bedding®", which uses two V-shaped aluminium action blocks that wedge the receiver firmly in place to prevent lateral shifts and also serve as recoil lugs. Because the front and back action screws are fastened through the centers of the action blocks, the blocks also functionally act as pillar beddings and allows the barrel to be free-floated. The rifle feeds cartridges into the chamber from a proprietary detachable rotary magazine via a push-feed mechanism employing dual cocking cams on the stainless steel bolt, which has three locking lugs allowing for a smaller 70° throw angle of the bolt handle. The trademarked "Ruger Marksman Adjustable™" trigger is a functionally two-stage trigger similar in design to the Savage AccuTrigger, which allows the user to adjust the weight of pull between {{convert|3|-|5|lb|kg|lk=on|abbr=on}} by means of a set screw on the trigger housing.[2] The rifle comes with a tang-mounted safety.[3] Ruger American RimfireThe rimfire line of the Ruger American series shares similar features and designs with its centerfire counterpart, including the Power Bedding (V-lugs only on the front block), the Marksman trigger and the tang safety, although it uses a unique stainless steel single-extractor rimfire bolt with a 70° degree bolt throw and having only eight parts (including the dowel pin and striker spring) for easier disassembly, and feeds exclusively from the famed BX series rotary magazines from the prolific Ruger 10/22 family of semi-automatic rifles.
