Burris Signature 30mm Medium Universal Dovetail scope rings (SKU: 420578) are a set of steel rings designed to mount a riflescope with a 30mm main tube on a Universal Dovetail base. The Pos-Align inserts centre the tube inside the rings, increase the contact area and protect the riflescope finish against damage. The included correction inserts also allow minor base and ring alignment errors to be compensated for without using the riflescope's internal adjustment range.
