Ruger 90340 Fire Sight Set 10/22 Red/Green Fiber Optic Sights

The Ruger 90340 Fire Sight Set transforms 10/22 accuracy with high-contrast fiber optic technology that gathers ambient light for fast target acquisition. This factory-engineered sight system eliminates the guesswork of aftermarket compatibility while delivering professional-grade performance.

What Makes This Different

Unlike generic fiber optic sights that require gunsmithing modifications, the Ruger 90340 drops directly into factory dovetails without drilling or tapping. The red front sight creates immediate focal contrast against the green rear aperture, following proven military and competition sight principles. Factory engineering ensures perfect alignment with 10/22 bore centerline for consistent point of impact.
