Only one real answer, Burris Signature rings..
Self aligning, won't damage the scope tube. With the cost of quality scopes, why use something that can (and ususlly does) scar up the scope tube? The other advantage is if you're short on elevation, the off-set ring kit provides additional elevation.. I needed them for my Burris 3-12x mounted on a 15" 7-30 Waters.
Worked great and the scope is still mint.
