SME's Scope Leveler Scope Mount makes a streamlined eye-pleasing appearance which blends in perfectly with traditional scope rings while helping to eliminate accuracy-robbing canting errors. Attaches to your riflescope like a traditional scope ring; halves clamp together with two steel Allen head screws. Its easy-to-see offset level helps make immediate corrections without taking your eyes off the target. The leveler is constructed of aluminum with a matte finish and reversible design that works for left and right handed shooters.
