I was wondering if anyone could explain (or post a good explanation) to me how to pick out a scope for my AR-15. I have a red dot scope and was looking into getting a Mako 5X magnifier for it so that I could shoot at longer distances. But then I realized, if I'm going to spend $130 on a magnifier.....why not just get a regular scope and switch it out with the red dot when I needed to? I know you can get a fairly decent scope from $80-$125, I think?
Now the issue, I have no idea what scope to buy. I don't understand the 3-9x-40 explanations, and all the numbers. Those of you with scopes on your AR-15, what do you use? I don't want to spend a whole lot of money, but would like to be able to shoot maybe a squirrel, or rabbit, or coyote at 200 yards? I know the .223 cal is a light and fast round, but am not too sure of it's capabilities. Thank you for your assistance.
