Fieldmouse is right as far as the legality of the matter goes but I still don't see much of an advantage to red dots over fiber optics. I can still see my sights well past legal shooting time with no problem. I think it's more of a gimmick than anything IMHO. However, if you shoot one and think it really helps then that's great. My motto is, "If it gives you more confidence in the stand then it's worth having".
