Ruger 90415 Rapid Deploy Rear Sight Black SR-22/SR-556/SR-762

The Ruger 90415 Rapid Deploy Rear Sight delivers instant backup sighting capability for Ruger SR-series rifles when primary optics fail. This spring-loaded folding sight automatically deploys when the primary optic is removed or damaged, ensuring shooters maintain target acquisition capability in critical situations.

What Makes This Different

Unlike fixed backup sights that remain permanently raised, the Rapid Deploy system stays folded flat against the receiver until needed. The spring-loaded mechanism activates instantly when the primary optic mount is removed, eliminating manual deployment steps. This design maintains a clean sight picture through scopes and red dots while providing immediate backup capability without tools or complex procedures.

Key Features

• Spring-loaded automatic deployment when primary optic is removed
• Low-profile folded position won't interfere with scope or red dot sight picture
• Precision-machined steel construction with corrosion-resistant black finish
• Windage adjustable rear aperture for accurate zero maintenance
• Direct bolt-on installation to factory Picatinny rail system
• Compatible with Ruger SR-22, SR-556, and SR-762 rifle platforms
• Positive lock mechanism prevents accidental deployment during normal use

Field testing demonstrates reliable deployment across temperature ranges from -20°F to 120°F. The sight maintains zero through thousands of folding cycles and withstands recoil forces from .308 Winchester cartridges. Competition shooters and tactical users report consistent performance during rapid transitions from magnified optics to iron sights. The corrosion-resistant finish handles extended exposure to moisture and cleaning solvents without degradation.
