b. Boresighting.

The distant aiming point

method of boresighting is used when the 14.5-mm

trainer is mounted on the tripod. To boresight the trainer

follow steps I through 5.

Step 8: Level the mount. There are two level vials on

the mount. With the tube pointed in the approximate

direction of fire, turn the traversing handwheel until one

of the level vials is directly over the rear leg. This vial will

be known as the "cross level vial". In this position the

other level vial will be near the right front leg and will be

known as the "horizontal level vial". The horizontal level

vial bubble is centered by turning the rotating collar of the

rear leg. The cross level vial bubble is centered by

simultaneously turning the rotating collar of the two front

legs either toward each other or away from each other.

Step 1: Center both the horizontal and the cross level

vial bubbles.
