Which upgraded IR do you have, the 850 Pro? I do not have the ATN, I have the Sightmark and mine will illuminate up to 150yds, but my version has the 940nm IR. The 850nm are supposed to reach 300 yards, but not sure if that is a clear picture at 300 to know what you are seeing. I am curious if others have any experience with a brighter IR, what range they are able to identify targets, black hog etc and know they are looking at a hog and not a black calf.. I have thought about adding an ATN HD Smart Pro for another AR build I will do this year.
