I second the burris rings, the best in the business, period. And as stated i only trust burris ring on my high end scopes or heck for any scope that isTxhillbilly said:If you only want/need 10moa,just buy a set of Burris Signature Zee rings and use the +/- 10 moa inserts on the rings.
It's cheaper than a good base,and they are the only rings that I will use on all my High $$$$ scopes,you will never get ring marks on them.
