I think peep sights are the wrong way to go!When you are young the eye is capable of shifting focus so fast that the brain integrates three different focal planes into a single image - much like a motion picture. As you age the ability of the eye to do this begins to decrease and by the time you are 50+ you just can't see sights and target concurrently. The more light you eye has to work with the smaller the iris gets and the less dynamic focal range you need from the lens of the eye. That's why older shooters always do better shooting at an uncovered range - more light.A peep sight reduces the available light reaching the eye. While it helps you center the front sight it dramatically reduces one's ability to hit under low-light conditions like dusk and dawn.As a COF I found it necessary to go to what my brother calls "fat-boy" sights. I made a front sight from a doubled-over silver dollar that is 0.125" thick and filed the rear sight notch wide enough so that the sight picture has clear space on either side of the front sight of equal width as the front sight. This gives my eye maximum amount of light to work with. The sights are cut in a Patridge pattern - square-topped front and square notch rear. The human eye can center a target on the top surface of a wide front sight very easily. The Sapergia brothers use a large round front sight and a very shallow V rear to very good effect from what I hear. Both approaches use the same principals of optics - give your eyes lots of light to work with!I have made fat-boy sights for about a dozen folks and every one basically said something like " #@!! $#@*! I can shoot my muzzle-loader again!"Best Regards,John Cholin
