Ruger 90270 4KHM Scope Ring 1" Medium Blued - 42mm Objective

The Ruger 90270 4KHM Scope Ring is a factory scope-mounting ring engineered to hold a riflescope securely to a compatible Ruger rifle. This single ring is machined from steel and finished in a durable blued coating that resists corrosion in field conditions. It is sized for scopes with a 1-inch main tube and accepts objective bells up to 42mm.

Standing at a medium profile of 0.937 inches, the 4B/4KHM height provides the clearance needed for standard objective lenses while keeping the optic mounted low over the bore. The steel ring body grips the scope tube securely, making it a dependable mounting solution for hunting and general-purpose use on compatible Ruger rifles.

Sold as a single ring, the 90270 pairs with a second matching 4KHM ring to complete a full scope mount. This is a direct Ruger factory component, giving shooters a reliable, factory-spec mounting solution without resorting to aftermarket rings.
