The Ruger 1 inch Medium Scope Ring (brand part number 90278) is sized to fit a scope with a 1 inch main tube and up to a 42mm objective bell without the bell contacting the barrel or receiver. It uses Ruger’s own scope ring mounting pattern for a factory-matched fit. Finished in matte black, it’s built to mount directly to Ruger’s factory integral scope base, no separate base required on rifles that ship with one.
