I have a new set of Burris Signature Series 30mm High Weaver Style Scope Rings. These rings feature the ***-align inserts that allow you to set the scope at 20moa instead of using a costly base. The scope rings do not require lapping & will not leave marks on your scope. Fits weaver style bases and scopes that have a 30mm tube and 44-56mm objectives. $50 shipped.
