I have williams WGRS peeps on a few of my White's. I have some with the gold bead and some with the fire site. I like the gold bead for target as it has a smaller diameter and the firesite for hunting as it is always easy to get the site picture if I am in the sun or the shade. I also have the new firesite ghost ring, I am not sure on this site yet I have not used it enough yet. The Williams peep is very durable and has not failed me yet.
