The Leupold STD 1″ super high rings are a pair of steel rings designed for one- or two-piece Leupold Standard bases, the most popular mounting system in the Leupold catalog.
The front ring engages with a dovetail and rotates into the base seat, while the rear ring is adjusted laterally by the windage screws: initial alignment is thus achieved during mounting, leaving the scope's elevation travel intact for ballistic compensation. The height is 1″, approximately 25.4 mm from the base plane to the center of the ring; the top screws should be tightened to 28 in-lb and the windage screws to 45 in-lb. Steel, gloss black finish; Leupold indicates the STD system for calibers up to .300 Win. Mag.
