I replaced my old Leupold Rings with these Burris Rings, using the same Leupold base. They are a universal fit. They provide great protection of the scope, preventing any torque that might damage the surface and the integrity of the scope. My former rings did just that, and they were mounted by a gun dealer who had mounted thousands of scopes in the past.
With these Burris rings I mounted the scope myself, and I was able to make necessary adjustments to align my scope's line of sight with my rifle's point of impact. After a few shots at the range and only a few clicks of the windage and elevation adjustments, I was shooting a one inch group at 100 yards - something my rifle has never done before with other scopes and rings.
The only feature I don't like about these rings is that the plastic inserts detract from the overall streamlined appearance of the rings. But that is a minor drawback compared to their great performance. I highly recommend these rings for a do-it-yourself-job with professional results.
