The open iron demands triple “visual accommodation,” the eye focusing on three planes: rear sight, front sight and target. Smart shooters learn to clearly focus on only two of the three: front sight/target. Of course the front sight must be optically centered in the notch of the rear sight for alignment. But with training and practice, the shooter learns to deal with a slightly blurred rear sight while maintaining a sharp front sight on target picture. When a SWAT team commander trained me to be a better marksman, he had me repeat “front sight-target; front sight-target; front sight-target” as the key to precise bullet delivery with open iron sights. Frame of reference is important. If the front sight optically overfills the rear sight notch, it is impossible to align it properly. It’s best to have a glint of light, if ever so minute, on either side of the front sight as it appears in the notch in order to assure that it is centered.

The peep sight requires only two points of visual concentration: front sight/target. Newcomers to the aperture sight work hard trying to optically locate the front sight in the center of the hole. This conscious level of aiming with the peep tramples on its simplicity and effectiveness. The human eye naturally seeks out the point of brightest light, pinpointing the front sight in the hole “automatically.” Ghost Ring rear sights come with a 191-inch and .230-inch inside diameter apertures. These are big. But as O’Connor pointed out, he removed the disc from his Lyman peep sights entirely, leaving a huge hole with negligible diminishment of group size. The name, Ghost Ring, tells it all. The rear sight (aperture) becomes nothing more than a halo to be ignored. It is supposed to look fuzzy. Simply line up that front sight on the target and squeeze off the shot. Work hard, and you lose. Let your natural eyesight take over, and you win.
