I did the same thing, went to Cabelas and bought a williams peep and screwed it in the same place as pictured. Only one hole aligned but it has held fine that way shooting 110 grain pyro. I had to use the orig sight that came with it in the same spot for some reason to get her on target at 100 yards. I did put lock tight on the one screw, but it has never shifted or been an issue. I love the peep as I am used to using a peep on my bow. Also, we can only use 1X scoped or dots here in Utah so cannot see using a scope over the peep. My only complaint is that the stock front sight is too wide at the base and tends to block out some of the picture when looking at deer sized target at 100 yards. After this season, I will fabricate a front sight that has a very slender base and a smaller dot kind of like a heavy duty straight pin. I will prob put a hood on it to protect it, but will make it a large hood- the diameter of my pointer finger or so. I would buy the front if anyone knows who sells them or where to buy them.
