The Burris XTR Xtreme Tactical rings were created specifically for the tactical shooter who put a premium on less weight and plenty of holding power. From smaller carbines to the most powerful magnums, Burris XTR rings will stand up to years of use and recoil. They are also great for hunting rifles, slug guns or muzzleloaders. Available in 1" and a choice of four ring heights, Burris Xtreme Tactical Rings will work with any Weaver and Picatinny-style bases. The extra-high 1" version is ideal for AR15/M16 flattop receivers where scope height is critical.
