Zeroing Tool [BETA] – Precision at Home, No Range Required

The Sentinel Works Zeroing Tool is an interactive calculator and printable target generator designed to make firearm zeroing accessible to everyday gun owners. By entering simple inputs like height-over-bore, desired zero distance, and the space you actually have available, the tool provides a precise point of impact (POI) offset and a downloadable 1:1 scale target. This allows users to sight in optics or confirm alignment safely and effectively, even in confined spaces like a backyard or indoor range.

Why It Matters

Zeroing is the foundation of accuracy. Without a reliable zero, even the best firearm and optic setup will perform inconsistently. Many shooters struggle because they don’t have access to long-distance ranges, or they want to validate their setup at home before heading out. This tool bridges that gap—offering a science-backed, geometry-based solution that converts short-range practice into long-range confidence.

Benefits for Firearm Owners

Train Anywhere: Accurately simulate longer-range zeros at just a few feet, making it possible to practice and adjust optics where space is limited.
Save Time & Ammo: Arrive at the range already dialed in, avoiding wasted rounds and frustration.
Build Confidence: See your point of aim (POA) and point of impact (POI) relationship visually, and print custom targets scaled perfectly to your firearm’s setup.
Promote Safety & Responsibility: Encourages owners to fully understand their weapon system before use, reinforcing Sentinel Works’ mission of responsible gun ownership and training.

With this tool, Sentinel Works empowers the community to take charge of their accuracy, no matter where they live or train.
