This is what I like about the copperjohn after doing some research on them. I like the copperjohn sights because they are easily adjusted for windage and elevation. They have big hex heads that you can tighten down snug and will not strip. They are of all aluminum construction and even the pin guard is aluminum. It has a hole tapped in the pin guard for mounting a light kit. The pins are very strong and birght and easy to pick up. The sight body is round and has a super bright orange tape around it and can be picked up easily in the peep and low light conditions. It is more reasonably priced than some of the other sights I have looked at. Hope this helps.
