I think I want to put a red dot on my Mini-14, but from what I read red dots are designed for use on crossbows, shotguns and pistols. Is this right? I want my Mini-14 to to be for short distance engagement, so I want to replace its scope with a red dot with the thinking that a red dot has faster acquisition and is more suitable for short distances. What do do you think? Also, for what distances are a 1x red dot for? I think I'd want some magnification to get out to 100 yards, right?
