Burris Optics 420211 Overview

Adjust the canting of your scope using the high Burris Optics XTR Signature Rings for Riflescopes. These rings accept 34mm maintubes, fit Picatinny/Weaver bases and rails, and hold the center of the scope 1.5" above the top of a rail or base. To assist you with canting, the rings include five pairs of Pos-Align inserts for 5, 10, 15, 20, 25, 30, and 40 MOA corrections. The inserts also help with centering and maximum scope-to-ring contact to increase gripping power without scratching your scope's finish. The rings can also be used to correct misalignment caused by off-center receiver holes or bases. The dual steel clamps with a full cross-through connection assure proper centering on Picatinny rails and add extra strength to the assembly.
