I checked them out at DSC last month. It's really hard to tell glass quality in those convention centers, but looks pretty decent, about where a Zulu 5 is. Robby Denning has a review of the 5's on Youtube you can check out to get an idea of how those fare. These should be in that ballpark from what I am told.
As far as the ranging, again, it was inside, so not much of a test. But it was fast and no problem. Cool thing is that the divergence on the beam is like 1.3x.6 IIRC from my discussion with Sig, horizontal oval shape. So small and smartly situated.
Should be getting some in a few weeks to try out. My contact at Sig is hitting well over 4k with these due to the much larger receptor surface, overall, pretty excited to check these out and run them with my son's BDX scope and my Kestrel.
