Ruger 4B30 Scope Ring 30mm Medium Blued Carbon Steel - Single Ring

The Ruger 4B30 is a medium-height scope ring machined from carbon steel with a polished blued finish. Designed to clamp a 30mm main tube on a scope with an objective diameter of up to 42mm, this is a single ring built to Ruger's standard for rifles equipped with factory-integral receiver bases.

The 4B30 is intended for Ruger rifles that come from the factory with integral bases machined into the receiver, including the M77, Hawkeye, and African series. The medium height provides enough clearance for standard 30mm main-tube scopes with up to a 42mm objective while keeping a comfortable cheek weld on the stock. The blued carbon steel construction matches the traditional finish on Ruger centerfire rifles and is built to hold zero under field recoil.

Sold individually as a single ring, the 4B30 is the correct replacement or build piece when you need to add or swap a top ring in an existing Ruger setup. Made in the USA to Ruger's factory specifications.
