Burris Ruger to Weaver Scope Ring Base Adapter Ruger 77, 1, 77/22,Redhawk, Blackhawk Black

This works for using Burris Sig Zee rings on Ruger 77/22 rifles. It provides more ring placements that might be needed on certain scopes and provides use of rings other than Ruger brand rings. Burris Sig rings have swiveling inserts that can increase elevation or correct windage problems and enable reticle to be close to center. I would not use the adaptor on other than 1" or 30mm Burris Sig rings.
