This guide details how to zero an EOTech holographic sight, presented by Karl Erickson, a former US Special Forces member. It covers selecting the optimal zero distance (50 meters recommended for tactical use), achieving a precise aiming point, co-witnessing with iron sights, establishing a stable shooting position, and making precise adjustments based on MOA calculations. The guide emphasizes confirming the zero at the intended engagement distance.

Quick Summary

Karl Erickson recommends a 50-meter zero for EOTech sights in tactical scenarios, providing an effective range up to 200 meters. For precision, dim the red dot and co-witness with iron sights. Adjustments are typically 0.5 MOA per click (1/4 inch at 50 meters), made with a screwdriver.

Frequently Asked Questions

What is the recommended zero distance for an EOTech sight in tactical situations?

For most tactical applications, Karl Erickson recommends a 50-meter zero for your EOTech sight. This distance provides an effective point-of-aim for targets out to approximately 200 meters, balancing ease of zeroing with practical engagement ranges.

How do you make precise adjustments when zeroing an EOTech sight?

EOTech sights typically have 0.5 MOA adjustments. This means each click moves the point of impact 1/4 inch at 50 meters. Use a screwdriver or multi-tool to turn the adjustment turrets, following the arrows, to align your group with the aiming point.

What is co-witnessing and why is it important for zeroing?

Co-witnessing involves aligning your red dot sight (like an EOTech) with your rifle's iron sights. This is crucial for quickly getting on paper during the zeroing process. If your red dot is already roughly aligned with your iron sights, you'll need fewer shots to achieve a precise zero.

How can you zero an EOTech sight if the click values are unknown?

If the click values are unknown, use 'bold corrections.' Fire a group, then make a significant adjustment (e.g., 10 clicks) in the direction needed. Observe how far the group moves on the target. This allows you to establish a unit of measurement to refine your zero without needing the manual.
