Buying and mounting facts
Manufacturer specifications
Useful for comparing size and setup requirements. The scope label on each fact shows whether it is tied to the exact SKU or only the model family.
Manufacturer receipts
productMark 4HD 2.5-10x42 M5C3 FFP TMR — part 183740Leupold ↗Scope labels matter: tested unit describes the evaluated optic, exact SKU maps a manufacturer product code, and configuration family applies to the documented model family without proving serial-level identity. A scope match can still remain an evidence lead when its authority or identity chain is incomplete.
