The sightron s6 is fully illuminated,. So I shot the S6 in a FT match today. It is a prototype or pre production, I shoot WFTF , I was shooting new gun and the new scope. I've found the ranging to be good, very repeatable, it doesn't snap, but it is easy to get used too. Some that have looked thru it think it is not as clear as other scopes. I think it is as clear as my Kahles. Granted this is a pre production and has been torture tested at Sightron. The clicks are great, positive no mush or slop and tracks amazing. The eye box is tight, which I personally like. The magnetic side wheel is tight and slack free, quite a nice bit of machining. When cranked up in the 90 temperature there is a lot of mirage, but at 60x you're going to see it with a scope designed 9 to 55 yards. Mirage is good for wind reading as long as you still see the kill zone.
So after a week or so, but only 2 real days testing in FT environment, I think it's working well. 62 shot match today only dropped 4 shots, of those 4 shots they were wind call errors on my part, no ranging errors. Managed 1st in WFTF and tied for match high with Scott Schneider, which is tuff to do. I can say I would focus on the block and when I move to the face plate which is a few inches off the front of the block, I could see a focus difference . Will see how it performs at pyramid cup in a few weeks.
