This expert guide emphasizes consistent shooting technique, using a stable rest, and making incremental adjustments based on three-shot groups. It clarifies that optic adjustments affect point of impact, while magnifier adjustments only center the reticle visually.

Frequently Asked Questions

What is the recommended method for initial firearm zeroing?

Start with a three-shot group to establish a baseline. Analyze the center of this group and make incremental adjustments to your optic (like the EOTech XPS2) based on its MOA per click value. Repeat until shots are centered.

How do you adjust an EOTech XPS2 sight for zeroing?

Zeroing adjustments are made directly on the EOTech XPS2 sight itself. Each click typically corresponds to 0.5 MOA. Calculate the difference between your group's center and the bullseye, then apply the necessary clicks up/down and left/right.

What is the difference between adjusting the optic and the magnifier?

Adjusting the EOTech XPS2 optic changes where the bullet impacts the target. Adjusting a magnifier only shifts the reticle's position within the magnifier's field of view; it does not affect the point of impact.

What shooting technique tips are important for zeroing?

Maintain a consistent grip and trigger pull, avoid flinching, and use a stable shooting rest. Reducing reticle brightness can also help achieve a crisper aiming dot for better precision.
