The XS Sights R3D are a 3-dot tritium notch-and-post night sight set designed to keep the front sight highly visible in a range of lighting conditions. The front sight incorporates a tritium lamp and a photoluminescent Ember Glow Dot that charges from ambient light and the front tritium lamp. The rear sight is a blacked-out, two-dot tritium design intended to provide contrast without outshining the front sight. These sights suit everyday carry, duty, and range applications where low-light sight visibility and fast, consistent sighting are priorities.
