I've used my Revic on a AR-10 in .308Win and on my 6.5 Creedmore and have shot over 1000 rounds combined without a failure hunting and shooting steel out to 1000 yds. I've had it over a year so it is their latest version. I've dialed up and down numerous times and the scope has been spot on every shot. My buddy, 3 other guys on the range, and I were very impressed at how it adjusted for atmospherics as the day changed. My buddy was constantly typing in the latest temp and distances in his ballistic calculator and I was just turning my elevation dial to the HUD distance setting without needing to do any calculations. The scope kept track of the atmospheric changes, my incline and my tilt automatically, so all I had to do was dial the changing distances. I really like this scope.
