XS DXT2 Night Sights offers the best front sight visibility in all lighting conditions. DXT2 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. DXT2 front sights use a patent-pending glow dot that absorbs light and glows in low light levels before it's dark enough to see the tritium. The dot-the-"i" sight picture prevents confusing the front and rear sights in high-stress situations. The wide field of view increases visibility of the front sight and of the threat downrange.
