eant the use of the _peep hole_
in the drift slide.

To use the peep sight:

1. Look through the peep hole at the target. (Fig. 7.)

[Illustration: Fig. 7]

2. Bring the top of the front sight to the _center_ of the peep hole,
_the top of the front sight being just under the bull's eye_. (Fig. 8)

[Illustration: Fig. 8

_Correct_]

_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_.

[Illustration: Fig. 9

_Incorrect_]

=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.

[Illustration: Fig. 11]

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.

The battle sight is the only sight used in _rapid fire_. In
unexpected, close encounters the side that first opens a rapid and
accurate fire has a great advantage over the other. Again, a soldier
on patrol generally has no time to set his sight, if suddenly attacked
at close range. The battle sight, may, therefore be called the
_emergency sight_,--the _handy_, _quick sight_. The soldier should,
therefore, become thoroughly familiar with the use of this sight.

_Battle sight_]

The _sighting notch_ in the slide with the rear sight leaf down, is
the same height as is the sighting in the drift slide when the rear
sight leaf is raised and set at 530 yards.

That is to say, _battle sight_ is equivalent to a sight setting of 530
yards. Therefore, in shooting with battle sight at objects nearer than
530 yards you must aim lower.
