I have it narrowed down to Warne QR, Leupold drop in quick release (not the weaver style) work best if you want to keep iron sights and Burris signature Z rings with inserts. I like the idea of Quick release so I can share scopes, but I like the added moa I can build into the burris rings with the inserts and they dont scratch the scope. They would go on a Warne base or the Leupold would be in the QR leupold base. Any thoughts or experiences? By the way it is going on a Encore.
