Yes, I've given some thought to just staying with Burris Signature Zee. Definitely my favorite rings I'm just not sure if they're the best choice for a platform that might get knocked around a bit.
Have you considered the Burris XTR Sigs? Beefy rings, with the Burris Sig inserts. I’ve got a few sets now- mostly for added inclination in the rings and how easy they are on scope tubes- all have been solid.
