I currently have some cheap rings that came with a 30mm tube scope i bought and they are too low. THey measure At.600. Does anybody know what the burris signature Zee (extra high) rings measure out to? I was told .420 but that doesn't seem right. If this is true, does burris make any taller signature zee rings? If not, who makes a ring around .650? thanks for your time!

According to the Burris book, the 30mm Signature Zee X-High measure out to be .455". That is the tallest Signature Zee ring that is made. You may want to look at the Warne rings.

Kelby or US Optics are good ones as well--not cheap is issue..
