Unique system puts an end to dinged, damaged, and misaligned scope tubes, plus holds scopes firmly against recoil. Steel outer rings with self-centering, synthetic inner rings, adjust to slight mounting variations so any 1" or 30mm scope is perfectly aligned. On bases without windage adjustment you get maximum usage of the scopes’ internal windage/elevation adjustment, closer lens alignment, and clear, sharp images.
