Big Dot Night Sights are specially designed defensive tritium sights that enhance the performance of your defense firearm. Utilizing a proprietary photoluminescent Glow Dot, these sights absorb ambient light and emit a glow in low-light conditions. The convex shape of the dot increases its surface area, enhancing light absorption and intensifying the glow, providing optimal visibility when it matters most. Crafted to be large and highly visible, these sights address common challenges such as aging eyes and deteriorating vision. Our testing has shown that the orange front sight is particularly effective in daylight, while the yellow variant shines brighter in low-light situations. The white dot, although non-glowing, is reflective, making it an excellent choice for both bright and low-light environments. XS Tritium Night Sights are designed to be big, bright and easy-to see in any lighting condition, day or night. Each sight is CNC machined from solid steel bar stock in our in-house machine shop, ensuring the highest quality and durability. We take pride in producing American-made products, with our tritium expertly inserted to guarantee top-notch performance. As a small, second-generation family-owned business based in Fort Worth, TX, we treat our customers like family. Our passion for firearms drives us to manufacture tritium night sights for shotguns. Additionally, we create gunsmithing tools, shotgun magazine tube extensions and optic mounts, as well as Ghost-Ring and optic mounting solutions for lever-action, bolt action and black powder long guns designed for hunting.
