Duration: 5:34

This video demonstrates how to properly sight in a handgun red dot optic. It covers the importance of periodic zeroing, using co-witnessing as a starting point, selecting the correct zero distance based on application, and using duty ammunition for final zeroing. The host also details the mechanical adjustment process and emphasizes that a shooter's individual grip and mechanics are crucial for a true zero.

Quick Summary

To zero a handgun red dot, start by co-witnessing with iron sights. Choose a zero distance based on application (e.g., 25 yards) and use your duty ammunition for final adjustments. Remember to tap the optic after adjustments and confirm zero accounts for your personal shooting mechanics.

Frequently Asked Questions

What is the first step to zeroing a handgun red dot?

If using suppressor-height sights, the first step is co-witnessing the red dot with your iron sights. This acts as an initial bore sight to get your shots on paper quickly before making fine adjustments.

What ammunition should I use when zeroing my handgun red dot?

It's critical to use your intended duty or carry ammunition for the final zero. Different bullet weights, like 115gr versus 147gr, have different trajectories that will affect your point of impact.

How often should I check the zero on my handgun red dot?

You should periodically check the zero on your handgun red dot. This is especially important after replacing the battery or at least once a year to ensure your firearm remains accurate.

What is the difference between mechanical zero and shooter zero?

Mechanical zero refers to the optic's internal adjustment limits. A shooter zero is when the optic is aligned with the point of impact based on how an individual grips and shoots the firearm, accounting for personal mechanics.
