I have a 2nd gen atn scope
I have a 2nd gen scope for hunting coyote. reasonable range with the built in IR flashlight, maybe 50 yrds. if it is a clear night you can see for several hundred yards. I havent played with any of the newer generation scopes, but i would say if it is for hunting get a IR spotlight they make it a lot easier to hunt.
For the most part the scope is never on the riffle. (it is bad to use them if there is light out) so it sits in my safe until i got hunting again and have to sight it in again. Kind of a waste but i like to kill the little dogs. so it has been worth it for me.
My scope did die on me once, i had to send it to ATN. they rebuilt it free of charge and payed for shipping both ways. there customer service was top notch in my opinion. But that was 4 or 5 years ago and that could have changed.
Now if they start selling thermal sights at reasonable prices soon i will be very happy.
