The SG20053Y from XS Sights are Tritium Night Sights that provide optimal front sight visibility in all lighting scenarios. This is achieved by combining tritium with XS\' unique, patent-pending glow dot. These sights are an excellent upgrade for home-defense shotguns, offering a high-contrast front sight that can absorb light and glow in suboptimal conditions.Optic Orange has been specifically designed to provide a high-contrast sight picture during bright light conditions, while also retaining its visibility as light levels decrease. The color blend primarily includes yellow with a touch of red to ensure visibility in low light when uncharged.The larger surface area of the convex dot helps increase light absorption, which greatly enhances the charging of the glow properties of the dot. This ensures that your sighting is clear and accurate, no matter the lighting condition.
