The Ruger 4B medium scope ring (brand part no. 90270) is a genuine factory accessory sized for a scope with a 1-inch main tube. Ruger designs it to clear a 42mm objective bell, and the medium height gives a typical hunting scope room above the barrel and receiver. It has a blued finish that matches the look of a blued Ruger rifle. The ring is sold individually, so a standard two-ring mount uses two of them.

Key Specifications

• The ring is sized for a 1-inch scope tube, the most common main tube diameter on hunting scopes.
• It is designed to fit a scope with up to a 42mm objective diameter, so the bell clears the barrel and receiver.
• Ring height is medium, a middle height that suits most standard objective sizes.
• The finish is blued, a traditional finish that blends with a blued receiver.
• It is sold individually, one ring per unit, so a pair takes a quantity of two.
