I need help.....I want to get a good scope for my m1a, but am not sure which one. I was in a academy sports going through all of the scopes and seem to be stuck on leopolds so far. The glass was just so clear and crisp. They didn't have a huge selection so I wanted to ask everyones opinion. I started to look online and see some are illuminated, etc. I have been looking at the mark 4 lr/t, but have heard of vortex and other models. What do you guys think? I want something for 5-1k yards. Thank you in advance.
