I prefer a pic rail, one that has the full slot all the way accross not the valley in the middle of the slots. the EGW heavy duty would be an example of what I like. Weaver makes one there are others. This way I have ONE mounting system on every gun I own. I can move and easily install a scope on another gun. If I want a load development scope on that gun, no problemo. I have one that stays mounted in leupold QRW rings bam its on.

for premium rings I like the nightforce ultra light titaniums. There are lots of others, weaver skeletons, leupold QRW's steel, aluminum, just lots and lots of options on rings. I don't see there being a heavier duty more optioned setup.
