2.6 Zeroing Procedures
Once the weapon’s iron sights have been zeroed, please refer to the section on Windage and Elevation
Adjustments (Section 2.1.6) to zero the HWS®. The following are some additional reference aids that
can be used during the zeroing process.
BORE SIGHTING
Bore sighting is a good preliminary procedure in achieving proper alignment of your sight to the
firearm. A chamber laser/ bore sighter is an aid in achieving collomation.
LIVE FIRE SIGHTING FOR AN M-4 OR M-16
To employ the aiming dot of the HWS® 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. Additionally there are custom targets for 25m zeroing used with the M-4 and
M16 (see Figure 7), and for Laser Bore Sighting (see Figure 8). Please visit the manufacturer’s website
at www.L-3com.com/EOTech or contact the manufacturer for copies of these targets.
