Frequently asked questions

Will this base work on both short-action and long-action Ruger American rifles?

This base is engineered for the Ruger American short-action platform. Long-action models have different receiver geometry, so verify your rifle model before purchase to ensure proper fit and alignment.

How much clearance does the extended length provide for larger objective bells?

Extended bases push the mount forward on the receiver, giving you more breathing room for 44–50mm objective lenses. Check your scope's bell diameter against your rifle's geometry to confirm adequate clearance before assembly.
