I have been using the CP Deadnuts 3 pin hunter for about a year now with almost nothing but good things to say about it. My only real "beef" is with the vertical adjustment system. It is a pain in the rear in my opinion. Two set screws and a wide vertical gap to move them in. I basically have to re-level the sight every time I move the pins up and down. I understand that this is probably there for that very reason but I would prefer some form of separate adjustment for that issue.
