I love the Williams Peep set up. It allows you to see most of the target you are shooting at. I just use a front fiberoptic bead and I like that, but some have switched to a KNS front crosshair sight which is about 1 MOA at 100 yards. In bright light they are great, but I tried it, and in shadow, I couldn't see the crosshair. However, some people love it. There are some other posts describing that set up if you do a seach.

I think you will love the rear peep. Not too expensive to try. About $26? dollars at cabelas.
