XS Sights R3D Green Night Sight for Springfield Hellcat

XS Sights’ R3D Night Sights deliver a traditional 3-dot tritium sight picture with notch and post configuration. The blacked out rear sight boosts contrast against the front sight for faster target acquisition. Choose between orange or green variants—each front sight ring features Ember Glow Dot Technology that absorbs ambient light and glows when conditions are dark. The R3D line ranks among the brightest night sight options available, performing effectively in both bright daylight and low-light environments. Green delivers maximum glow intensity and performs best in low-light settings, while orange provides superior contrast in bright conditions while maintaining adequate visibility after dark. The front sight tritium lamp is brighter than the two rear sight lamps, which prevents confusion between front and rear vials in minimal or no-light situations. The front blade measures 0.145″ (3.68 mm) wide, and the rear notch spans 0.170″ (4.32 mm) wide, both dimensions engineered to enhance front sight visibility. Installation uses standard sight pusher tools or can be completed with a hammer and punch. These sights are designed to fit the Springfield HellCat OSP.
