c. Visually check rear sight to ensure it is centered after making adjustments. Also, ensure the rear
sight is set in the short-range (0 - 2) position.
4. Assemble rifle; refer to TM 9-1005-319-10.
5. After the rifle is assembled, center rear sight, place at the 300 meter mark, and perform the following
check:
a. While looking at a light background, obtain good sight alignment.
b. If the hole in the rear sight aperture appears oval instead of round, the rear sight base or upper
receiver should be replaced. To determine which part requires replacement, replace the rear sight
base first. If this does not resolve the problem, replace the upper receiver.
