The 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 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 steel action blocks that wedge the receiver firmly in place to prevent lateral shifts and also serve as recoil lugs.
