Weaver's popular Grand Slam Rings were recently revamped for an impressive, sleek, modern new look. Weaver's legendary cross-lock design provides the ultimate in scope lock-down. Made of solid steel, these rings stand strong against aggressive recoil. Their Windage Adjustable Rings allow for a range of crosshair movement, right and left, when sighting in your scope. To top it off, Weaver's newly-designed Grand Slam Rings are proudly made to exact tolerances in the U.S.A.
