Looking to get my first spotting scope. I'm thinking a 20-60x adjustable. General idea is to start shooting 200 to 300 yards with my AR, and be able to tell what the heck I'm hitting. I'd like to spend under $200. I assume there's going to be a lot of junk out there. Anyone have recommendations? What's good? What to stay away from? Do I need to adjust my price range?
