optics for my AR15
I bought my first AR15 at the first of yr. I did not do my research before I bought it.. :-( It had a rubber armored tactical Target sports 3-9x42. I have done some research and now thinking I should have got one of these red dot scopes then add a magnifier. Could some one please guide me in the right direction. I am shooting anywhere from 25 yards to 300. Though I am not that good at far distance yet. Anyways should I get one of these red dot eotec or aim point red dot scopes or is what I have ok?? I don't like it for short distances because it's harder to locate target fast enough. That's why I am considering one of these red dot scopes??? HELP PLEASE!!!
