1" Maxima Quick Detach Low Weaver Style Matte Finish by WARNE SCOPE MOUNTSThe Maxima QD Rings sport the unique Warne indexable lever system which allows the user to remove the optics from the rifle then reattach it without the loss of zero and as well as allowing the location of the lever to be indexed once the rings are affixed to the bases. After the levers are tightened and simply pull out on the lever and turn it to the desired location then let it snap into place. When used on the all steel Warne Maxima Bases and we guarantee accuracy of within 1/4 of an inch at 100 yards when removing and reattaching the optic. Also unique to the industry and the Maxima QD Rings have a square stainless steel recoil control key. This ensures a positive recoil engagement surface across the full width and depth of the recoil slot in the base. The recoil control key guarantees that the rings will not shift or move under fierce recoil and also protects against peening or swaging when mounted on aluminum bases. Ring Height .250"
