ZEROING
IRON SIGHTS
17. General. Zeroing the rifle is accomplished through adjustments to both the front sight
and the rear sight. See Figure 4-7.
18. Adjusting the Rear Sight. The sight on the DIS and Back-up sights has two aperatures.
The large aperature (battle sight) is used for shooting at short range or during low light
conditions. The small aperature can be used at all ranges. To zero the sight in azimuth or to
adjust windage, depress the detent with a punch or suitable object and rotate the windage drum
left or right. To move the mean point of impact (MPI) to the right: rotate the windage
drum clockwise.
NOTE
The DIS or back-up sight is fitted to the rifle with the windage drum on the right, when
viewed from the rear.
19. Front Sight Adjustment. To zero or adjust elevation, depress the front sight detent with
a punch, and rotate the front sight post clockwise or counter-clockwise. To move the MPI up:
rotate the front sight clockwise.
