LIVE FIRE SIGHTING FOR AN M-4 OR M-16
To employ the aiming dot of the Reflex Sight reticle from 10 to 300 meters, the sight can be
zeroed at 25 meters using a standard M4/M16 military zeroing target. With the dot aimed at
center mass of the target, the sight should be adjusted so the round lands approximately 1 cm
below the point of aim at 25 meters. This method of zeroing ensures hitting a target at 100-200
meters where fine tuning should be conducted.
