Warne Tactical 30mm Scope Rings - All Heights, Black Matte Warne Tactical Rings are made to 1913 mil-spec Picatinny (Weaver style) dimensions. They feature a stainless steel recoil lug, three torx style fasteners on top and a Hex style clamping nut that works with a 65 in/lb torque wrench but, also fits a socket wrench, crescent wrench, or pliers in an emergency. The Quick Detach system always returns to zero when removed and re-installed. Set up different scopes on the same rifle and change with the shooting conditions... Or, just use the QD feature rings to bring along an extra "just-in-case" already sighted in back-up scope!
