I have no idea what type rifle a DMR might be.
However, I do have some experience with fixed power 6X scopes, having mounted one on my Savage .30-06 a decade ago. I'm convinced that the fixed 6X is one of the most under-appreciated scopes on the market, and there aren't many companies who make them.
Leupold has their fixed 6X, as does Weaver at about half the price. Personally I like the fixed 6X. It's got plenty of magnification for field use, it doesn't have as many moving parts as a comparable variable scope, and there's nothing to fiddle with, so you don't fiddle with it. It simply works. My 6X is a Weaver and it's accounted for several game animals and a couple of reams of target paper. I like it a lot.
