With the growing popularity of the Ruger American line of rifles, adding their scope bases to our lineup was a natural choice. Crafted from a 1-piece of T7075 aluminum and precision-machined in-house on our state-of-the-art equipment, these bases are engineered for a perfect fit and built tough enough to keep your rifle securely in place, even under the most demanding conditions. Designed to provide the elevation needed for longer shots, each base is finished with a durable type III black hard-coat anodizing. The package also includes the required wrench for easy and precise tightening of the clamp screws.
