Be sure to get the top of front sight, as in [Fig. 8], and not the bull's eye, as in [Fig. 9], in center of the peep hole.

Advantage of the peep sight. The advantage of the peep sight over the open sight is due to the fact that it is easier to center the top of the front sight in the peep hole and thus get the same amount of front sight each time.

For example you know at once, without measuring, that the dots in the circles, [Fig. 10], are not centered, and that the one in the circle in [Fig. 11], is.

After a little practice, in looking through the peep hole the eye almost automatically centers the top of the front sight.

Disadvantage of the peep sight. The disadvantage of the peep sight is that its limited field of view and lack of readiness in getting a quick aim with it limit its use to those stages of the combat when comparative deliberation will be possible.

(c) Battle sight. By battle sight we mean the position of the rear sight with the leaf down. There is a sighting notch on the top of the leaf, or rather on top of the leaf slide which works up and down the leaf.
