The Ruger 90224 Scope Base Adapter transforms your Ruger Mark II, III, IV, or 22/45 pistol into a precision optics-ready platform. This factory-engineered adapter eliminates the guesswork of aftermarket mounting solutions while maintaining the firearm's original reliability and accuracy standards.
What Makes This Different
Unlike universal adapters that require permanent modifications, this Ruger-manufactured base integrates seamlessly with the pistol's existing frame design. The precision-machined aluminum construction provides a rock-solid foundation that won't shift under recoil or extended use. Factory tolerances ensure proper alignment between the bore axis and mounted optics, eliminating the accuracy issues common with generic mounting systems.
Key Features
- Factory Ruger engineering ensures perfect fit on Mark II, III, IV, and 22/45 models
- Aircraft-grade aluminum construction with corrosion-resistant silver anodized finish
- Standard Weaver/Picatinny rail compatibility accepts most red dots and scopes
- Low-profile design maintains the pistol's balanced handling characteristics
- Precision-machined mounting surfaces eliminate play and maintain zero

- Reversible installation allows return to iron sights if desired
This adapter excels in competitive shooting environments where consistent optic placement is critical for accuracy. The robust aluminum construction withstands the repetitive cycling of high-volume training sessions while maintaining zero retention. Hunters appreciate the ability to mount low-power scopes for extended-range small game hunting, while recreational shooters benefit from faster target acquisition with red dot sights.
