I picked up a 16" flat top AR this weekend that is missing it's rear sight. It has the standard front sight assembly like on the A2. I would like to put on a reliable rear sight that is not going to break the bank as this will mainly be used for plinking with the kids. It will probably get a red dot or low power scope as well, depending on usage. So I'm looking for recommendations on decent rear sights. I'm not opposed to a carry handle, rail unit like the RRA, or just a small fixed or flip up sight. Main thing is it should give repeatable adjustments.
