Though these are for a flattop, it's not an AR, but a sub. So, the range beyond, say, 200 yards (100 is more like it) is not important. I would like them folding, since I will be using primarily a red dot . BAsically, I don't need to buy a fancy one, since I don't need the range. It would be handy, however, if they used AR type post and ring, so I could reasonably buy night sight inserts. Note that I need both front and rear.
I know there are many out there, and so many to wade through. If it were an AR, I'd probably just go GGG but, in this case, don't need to spend that. Finally, I'd like decent size knob attachment, rather than allen screws.
