I have a friend that is looking for a quality scope to buy her husband for his AR. I just have inexpensive red dots on mine as all I use them for are general plinking but I know there are some quality ones available. He will probably be shooting at 100 yards max and the budget would be less than $500. If you have a suggestion of one that is over $500 please keep it to yourself because she has a budget of $500 and isn't going to "save up" and buy scope "X" because it has an extra doodad on it. $500 is the budget.
