Bought this Night vision a few years ago for $4k. I never really used it much. Mounted it to my ar10 .308 with a vortex viper 4-16x44 worked really good and was going to be a coyote hunting setup but never really go around to it. It works really well and is pretty slick! I can’t imagine there’s is more than 30 mins to and hour of run time on the tubes
