10m Range Zeroing
In the zeroing process, groups of three single shot rounds
are fired at a target. After each three rounds, the center of
the group has to be determined.
The 10mZ (800) line is to be used with the M249 and M240B
machine guns when firing the 10 meter exercise as part one
of the qualifying course. The trajectory of the 5.56 and 7.62
round are equal at this aim point and distance to target.
Look through the telescope and align the reticle's 10mZ zeroing mark
on the center base of the aiming points on the basic machine gun
