For about 4 years I assembled a variety of my own versions of a hind sight style sight, only with much better quality componets and some of my own making. Eventually, I decided that I don't need a peep or a rear sight. I'm shooting better than ever without either, especially at longer ranges. The problem with the hind sight concept is that I had to drop my anchor point to line up 30, 40, and 50 yard front pins with the rear sight. This created windage accuracy problems. I even designed my own rear sight with several pins to avoid the anchor issue. In the end, using only a 5 pin front sight with a kisser button, a consistant anchor, and no peep is what works best for me. The most important thing for consistant "real world" accuracy while hunting is to practice in all conditions I plan to hunt in. I shoot 30' up a tree in the wind, rain, snow and low light while wearing my hunting gear, especially gloves and head wear. So far, I haven't missed a deer kill since I started practicing this way year round.
