The DXT2 Big Dot Tritium Night Sights drive focus to the front sight using a high-contrast front and a V-notch rear for an unobstructed view of the front sight. These sights use a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. Optic Orange is designed to offer a high-contrast sight picture when shooting in bright light conditions and maintain visibility in decreased light. Dot-the-“i” sight picture with a tritium dot in the front sight and tritium bar in the rear, prevents confusing the front and rear sight in high-stress situations.
