Find My Scope
Answer five normal-person questions and get three explainable scope configurations without decoding the industry first.
Source-backed utilities
Tools
Calculators that expose their assumptions, plus living databases built from manufacturer documentation and official agency sources. Every result tells you what it knows, what it models, and what still needs to be checked on the actual equipment.
Scope Ring Height Calculator
Convert objective bell, tube, rail, and clearance measurements into both published ring-height conventions.
BDC Ballistics Calculator
Calculate G1/G7 trajectory and wind, print a range card, and map custom MOA or MIL reticle marks to predicted distances.
Maximum Point Blank Range Calculator
Find the zero that keeps a load inside a chosen vital zone for the longest distance, with near and far zeros plus a printable verification card.
Zero-Distance Visualizer
See how velocity, sight height, and zero distance shape a transparent gravity-only path relative to line of sight.
Red Dot Fit & Comparison
Verify one optic or compare three on the same firearm by plate path, hardware notes, co-witness limits, and evidence confidence.
Rangefinding Optic Laws
Rifle scopes, crossbow scopes, and electronic bow sights across all 50 states.
Scope Drop-Test Database
One record per evaluation, one column per stage, with untested stages left visibly untested.
Optic Passport Compare
Compare up to three configurations by identity confidence, source coverage, sample size, and every indexed zero-retention stage.
Optic Passport Registry
Permanent configuration records that keep source evidence, test history, and unresolved SKU details attached to the right optic.
