Leupold Dual Dovetail (DD) bases and rings represent one of our most robust mounting systems, engineered for standard to magnum caliber rifles with high recoil. This particular model is specifically designed to fit an Smith & Wesson classic and is notably favored for use with handguns and large caliber rifles. Our steel DD rings employ a twist-and-lock mechanism to ensure a secure connection with either 1-piece or 2-piece DD bases. The dovetail feature on both the front and back of the mount facilitates precise sight alignment. The rings are available in a variety of heights and with certain scopes and rifles, the DD system can position your optic close enough to the receiver to resemble an open sight. The connection between your scope and firearm is of utmost importance, which is why our mounts are as rugged and reliable as the Leupold optics they support. With an extensive selection of mounting systems available, you are certain to find the ideal match for your firearm and shooting style. Manufactured in the USA and guaranteed to withstand a lifetime of use, Leupold mounts are designed to never disappoint.
