Does anybody have any ideas for a value of a US Optics SN-2 3.8-22 scope. From what I can find out, it is 10-15 years old with a 58 mm objective. I know condition plays a factor, but I am looking for best case. I found one at a local pawn shop. I know they have it marked too high. I'm trying to figure out by how much though. Maybe a better question is it something worth considering?
