If you're mounting a mid-range to high-magnification scope on a modern rifle, the Ruger 90318 4K Medium 30mm scope ring delivers the solid, no-nonsense engineering you'd expect from a factory Ruger accessory. These matte stainless steel rings are built to handle scopes with objective lenses up to 42mm in diameter—a practical sweet spot for hunting optics and precision rifles that don't need extreme light gathering. The 30mm tube diameter is the industry standard for serious hunting and range work, and Ruger's medium height positions your scope at the right cheek weld for most modern rifle builds without requiring riser rings or awkward head positioning.
Ruger factory scope rings earn their reputation by doing one thing well: holding your optic securely and repeatably, season after season. These rings won't turn your rifle into a precision long-range platform, but they won't hold you back either. The matte stainless finish resists corrosion in the field and won't catch glare on the hunt. If you're running a Ruger or any rifle with standard Picatinny rail spacing, these rings integrate seamlessly as the no-compromise choice.
Scope rings are your mechanical link between rifle and glass—cheap rings translate to zero shift, lost confidence, and wasted ammunition. Ruger's 4K design has earned shooter trust by being reliable and repeatable, which matters whether you're zeroing at the range or setting up for opening day. This is the kind of accessory that disappears into your setup and just works.

Frequently Asked Questions
What size objective lens will these rings accommodate?
The Ruger 90318 4K medium rings handle objective lenses up to 42mm in diameter. This covers most popular mid-range hunting and tactical optics without requiring custom spacing or riser rings.
Are these rings suitable for hunting rifles?
Yes. These are factory Ruger rings designed for rifles with standard Picatinny rails. The medium height and 30mm tube diameter work well for hunting scopes and general-purpose rifle optics.
