Leupold Dual Dovetail (DD) bases and rings are one of our strongest mount systems, designed for standard to magnum caliber rifles with high recoils. This model specifically fits a Remington 700 and is especially popular for handguns and large caliber rifles. Our steel DD rings use a twist-and-lock action to ensure a strong connection with 1-piece or 2-piece DD bases, while the dovetail feature on the front and back of the mount allow for a precise sight-in.
