The Burris XTR Xtreme Tactical Rings are all about point-of-aim security and durability. The super-strong yet surprisingly lightweight, six-screw aluminum rings anchor scopes in place on any Picatinny rail or Weaver-style base to deliver unfailing return-to-zero. Designed and built for the rigors of tactical shooting and massive recoil, they are not out of place on varmint rifles or big game rifles that may be exposed to the abuses of hard hunting and magnum recoils.
