Ruger 30mm Medium Scope Ring, Matte Black

The Ruger 30mm Medium Scope Ring (brand part number 90321) is sized to fit a scope with a 30mm 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.
