The Ruger 90278 4BHM scope ring for M77 Hawkeye African rifles is a genuine factory accessory engineered for hunters and shooters who demand reliability from their rifle setup. Designed to secure 1-inch tube diameter scopes with a 42 MM objective lens, this medium-height ring pairs authentic Ruger engineering with a classic matte blue steel finish that complements the Hawkeye platform and weathers field use without flashy glint. Whether you're mounting an optic for dangerous-game hunting in Africa or setting up a dependable long-range rig, a quality scope ring is foundational—and OEM-matched rings eliminate guesswork about fitment and stability.
Ruger factory rings are manufactured to tight tolerances and integrate seamlessly with M77 Hawkeye dovetail or picatinny mounting systems, giving you confidence that your scope won't shift zero during recoil or after a tumble off a vehicle. The matte finish resists corrosion and pairs well with field-ready rifles, avoiding the reflective surfaces that can give away your position on a stalk. If you're already invested in a Ruger Hawkeye or M77, using genuine Ruger rings means you're not compromising on quality or accuracy—you're investing in a match that works.
This is a single ring; if you need a complete two-ring mounting solution, you'll want to source both medium rings separately or pair this with a matching Ruger ring. For hunters and marksmen who prioritize proven reliability over brand-name novelty, Ruger factory optics accessories remain a straightforward, no-nonsense choice.
