Sig Sauer X-Ray 3 Night Sight Set #6/#8 Green Tritium Square Notch
The Sig Sauer X-Ray 3 night sight set pairs a #6 green tritium front sight with a #8 square notch rear sight to give you fast, reliable target acquisition in any light. Whether you're working low-light duty shifts, hunting from dawn to dusk, or training at the range across changing conditions, these tritium sights stay visible and consistent—no swapping between day and night setups. The three-dot tritium system glows bright in darkness and shifts to white in daylight, keeping your sight picture intuitive whether the sun is up or down.
Built around steel construction, the X-Ray 3 sights are engineered to survive recoil, harsh cleaning solvents, and the elements without losing zero or performance. The blacked-out rear sight and high-contrast front sight design cuts glare and speeds up target location, especially in poor visibility. If you depend on your firearm for work or sport, these sights are built to stay at peak function for over a decade of service.
The square notch rear paired with the green tritium front is a field-proven sight picture favored by shooters who value speed and clarity. This set delivers the durability and optical performance serious shooters expect from Sig Sauer's tested optics line.
