3.7.1. Aiming and firing
To aim, align the eye, diopter or battle sight, foresight
and target. When using the diopter, ensure that the peri-
phery of the foresight tunnel and the diopter aperture are
concentric.
At all ranges, the foresight should be aimed at the center
of the target. Firing is therefore to point of aim.
