The Ruger Scope Ring (brand part number 90316) is a single high-height 30mm ring built by Ruger / Sturm, Ruger & Co. for its factory integral scope-mounting system, fitted to the Ruger M77 Hawkeye and African rifles. Machined from stainless steel and finished in Target Grey, it’s sized to clamp a 30mm scope tube while clearing a 52mm objective bell without contacting the barrel. Because Ruger bolt guns cut the mount directly into the receiver, these rings drop straight on without a separate base, keeping the whole setup lower and more rigid than a two-piece rail. It’s a factory-correct way to mount glass on a Ruger rifle without hunting down third-party mounts.
