I want to get a new rear sight for my AR. It has an A2 front sight post on it and the upper is flat top. I have a cheap carry handle on it, but it is not very good quality. Are there any rear iron sights available in this price range that are good quality? Or would I be better off shelling out a few extra $$ for an aimpoint knockoff red dot? Wanna kill these ads? We can help!
