I recently got an mp15or and need some sights for it. Anyone have any suggestions. I figured I would use a red dot of some sort and put some flip up iron type sights on it. Not sure in which order but I do need something. That said at this time I dont have 500+ bucks for a nice red dot and am willing to upgrade later. For iron type sights I am not sure whether to get the magpul flip ups or maybe troy flip up sights. What do you guys like for sights, any suggestions are appreciated. It will mostly get used at the range and maybe some classes for now.
