XS R3D Night Sights offer a traditional 3-dot tritium sight picture, featuring a green tritium front sight and blacked-out rear sights for increased contrast. The Ember Glow Dot Technology allows the front sight to absorb ambient light, glowing brightly in low light conditions. The front tritium lamp charges the Ember dot, ensuring it remains brighter than the rear sight for optimal focus downrange. These sights are designed to provide fast and accurate shooting in both bright and low light environments.
