XS Sights R3D Suppressor Height Green Night Sight for Glock 48

XS Sights R3D Night Sights deliver a traditional 3-dot tritium sight picture with a notch and post design. The blacked out rear sight increases contrast against the front sight post. Choose between orange or green front sight ring, both equipped with Ember Glow Dot Technology that absorbs ambient light and glows in low light conditions. The R3D line offers the brightest performance for fast, accurate shooting across both bright and low light environments. Green provides the best option for low light shooting with the brightest glow intensity. Orange delivers superior contrast in bright light settings while maintaining visibility when light is low. The front sight tritium lamp is brighter than the two rear sight lamps, which prevents confusion between front and rear tritium vials in low or no light situations. The front blade measures 0.145″ (3.68 mm) wide, and the rear notch measures 0.170″ (4.32 mm) wide, enhancing front sight visibility. Installation uses standard sight pusher tools or a hammer and punch method, though filing the rear sight may be required for proper fit. These sights are designed for Glock models 43X & 48 and function at suppressor height, providing lower third co-witness with Glock factory cut and RMR.
