I have a night vision scope that I have used a few times over the years. With the IR on you can see pretty much anything in a field that is in the 100 to 250 yard range.. basically it is like a scope with minimal magnification but good clarity at night.. especially a clear night with a good moon.
you can see to sight it in during the day. But generally you need to leave it on that gun and not try to switch it around because it can be a pain to sight in over and over again.
Willing to trade for just about anything:
Ammo in general
guns in general
