Zeroing a night vision scope follows the same basic principle as daytime zeroing but with some practical differences.

1.     Step 1: Confirm the mounting system is stable and the scope is properly torqued to spec.

2.     Step 2: Use a target at a known range (100m is standard). Night vision targets are available with highly reflective or IR-reflective surfaces that are easier to see at night — or use a standard paper target illuminated by a low-powered IR flood.

3.     Step 3: Fire a group from a supported position (bipod or sandbags). Identify the point of impact relative to point of aim.

4.     Step 4: Adjust windage and elevation in the standard way. Most night vision scopes use MOA or mil adjustments identical to daytime scopes.

Key differences from daytime zeroing:

•        Light levels affect visual precision — zero in conditions representative of how you’ll actually use the scope

•        If using a clip-on unit, zero with the clip-on attached; the clip-on shifts point of impact and must be included in zeroing

•        Record your zero settings separately for day and night configurations if you switch between them

Always verify zero at a live range before any hunting or professional deployment.
