Burris Xtreme Tactical 30mm High Scope Ring - Matte Black - Xtreme Tactical rings were created specifically for the tactical shooter who puts a premium on less weight and plenty of holding power. The massive strength of a 6-screw ring is combined with lightweight yet thick cross-section aluminum, so from smaller carbines to the most powerful magnums, XTR rings will stand up to years of use and recoil. They are great for hunting rifles, slug guns or muzzleloaders. Xtreme tactical rings work with any Picatinny or Weaver-style base and are ready for the heaviest of scopes, massive recoil and severe usage.
