This guide details how to adjust the windage and elevation on an EoTech Holographic Weapon Sight (HWS). It explains the location of the adjustment knobs, the tools required for adjustment (screwdriver, coin, or spent brass), and the direction to turn each knob to achieve desired point of impact changes. The video emphasizes ensuring the sight is properly mounted and collimated before making adjustments and checking security after initial firing.

Quick Summary

Each click of the windage or elevation adjustment on an EoTech HWS sight changes the point of impact by 1/2 minute of angle (MOA) at 100 yards. This equates to 1/4 inch at 50 yards and 1/8 inch at 25 yards. A full rotation shifts impact by 10 MOA (5 inches at 50 yards, 10 inches at 100 yards). Use a screwdriver, coin, or spent brass for adjustments.
