Ruger 90321 Hawkeye Medium 30mm Matte Blue Steel Scope Ring for Rifle

The Ruger 90321 Hawkeye is a single 30mm scope ring built for rifles that demand a solid, no-fuss mounting solution. If you're assembling a hunting rifle, setting up a range gun, or doing a scope swap, these medium-height rings provide the straightforward functionality that shooters rely on—no marketing gimmicks, just proven engineering designed to keep your optic steady and your zero consistent.

These rings are machined from alloy and finished in matte blue steel, giving them a clean, durable appearance that complements most modern rifle platforms. The single-ring design simplifies installation and works well for shooters who prefer minimal weight and a cleaner sight line on their receiver. At 0.150 pounds, they're lightweight enough that they won't affect rifle balance, yet rigid enough to handle the recoil and vibration of serious shooting.

The 30mm tube diameter accommodates the vast majority of mid-to-premium hunting and tactical scopes in common circulation. With a height of 0.9 inches and the ability to accept objective bells up to 42mm in diameter, the Hawkeye ring strikes a practical balance—tall enough to clear most rifle actions and foregrip designs without creating a high cheekweld, modest enough to keep your scope in a natural shooting position. If you're building a rifle around a quality 30mm optic and want a ring that does its job without fuss or failure, the Ruger 90321 delivers.
