Description
The Ruger 90278 4BHM is a single medium-height scope ring built to mount 1″ tube riflescopes with objective lenses up to 42mm. Machined from steel and finished in Ruger’s signature Hawkeye Matte blued coating, this ring provides a solid, low-glare mounting point that pairs cleanly with factory-blued and matte-finished barrels.
Designed for Ruger M77 and Hawkeye pattern rifles, the 4BHM Medium ring gives just enough clearance to clear a 42mm objective bell without sitting the optic too high. Sold as a single ring, it lets you replace a lost or damaged ring or pair it with a different height ring to dial in your preferred cheek weld.
Engineered by Ruger for a precise scope-to-rail fit, the 4BHM is a simple, dependable mounting solution for any Hawkeye-pattern rifle.
