The DXT2™ Big Dot® Night Sights were made for to provide exceptional front sight visibility in all lighting conditions. Available in two colors - Optic Yellow™ and Optic Orange™ - the DXT2 Big Dot sights drive focus to the front sight (and thus to the downrange threat) using a large, high-contrast front and a V-notch rear sight for an unobstructed view of the front sight.
The Big Dot front sights use a patent-pending colored glow dot that absorbs light, causing the sight to glow before it is dark enough to see the tritium center. The glow dot also stores energy enabling it to glow brightly for many hours. The V-notch rear sight features a vertical white stripe with a tritium vial at the center, creating a dot-the- “i” sight picture for fast and accurate target acquisition in high-stress situations.
Optic Yellow is the most visible color in low light and is a direct replacement for the first-generation white Big Dot sight. In bright light, Optic Yellow outperforms white because it doesn’t wash out on light backgrounds. Optic Orange is the best for bright light settings such as shooting outside in daylight and offers a high-glow intensity that maintains visibility in decreasing light levels. These Gen 2 Big Dots are four times as bright in low light as the Gen 1 Big Dots thanks to the XS Sights patent-pending glow dot. This increased brightness is due to pairing the convex dot with photoluminescent properties. The outward curve of the dot increases the amount of surface area, exposing the dot to more light, and the optical clarity amplifies light absorption, which increases the excitement of the photoluminescent properties.
