Frequently Asked Questions

Will this fit my rifle?

This scope base is built specifically for the Ruger American short-action receiver. Confirm your receiver matches that action/model before ordering, since scope mounting hardware is not interchangeable across unrelated actions.

Do I need gunsmithing tools to install this?

Installation uses standard hand tools (a torque wrench or hex driver is recommended); no drilling or gunsmith fitting is required for the Ruger American short-action receiver interface.

Does this come with mounting hardware?

Yes, the mounting screws needed to attach it to a compatible receiver or rail are included.
