The Ruger 90288 4KO Offset Scope Ring delivers precise 45-degree offset mounting for tactical optics configurations. This silver-finished medium height ring accommodates 1-inch tube scopes while maintaining the structural integrity needed for rapid target transitions and backup sight deployment.
What Makes This Different
The 4KO offset design positions optics at exactly 45 degrees from the primary sight line, enabling shooters to cant their rifle for instant backup optic access. Unlike standard rings that force compromises between primary and secondary sights, this offset configuration maintains optimal eye relief for both positions. The medium height specification provides 0.900-inch clearance from rail to scope center, accommodating most standard objective lens diameters without interference.
Key Features
- 45-degree offset angle for rapid sight transitions
- 1-inch tube diameter compatibility with medium height clearance
- Silver anodized aluminum construction for corrosion resistance
- Picatinny rail mounting system with secure clamping mechanism
- Precision-machined surfaces ensure consistent scope alignment
- Low-profile design minimizes snag hazards during tactical operations
- Compatible with red dot sights, magnified optics, and backup iron sights
Field performance centers on the ring's ability to maintain zero under recoil while providing repeatable return-to-zero when switching between primary and offset optics. The offset mounting angle works effectively for close-quarters engagements where magnified optics become limiting factors. Competitive shooters utilize this configuration for rapid transitions between precision shots and close-range targets. The anodized finish resists wear from repeated weapon manipulation and environmental exposure.
