Sig Sauer X-Ray 3 Night Sight Set - Green Front & Rear Tritium #6/#8 Round Notch

The Sig Sauer X-Ray 3 night sight set brings together function and reliability for shooters who need fast, accurate target acquisition in any light. These tritium sights pair a green front sight with a rear sight featuring a round notch design, giving you the contrast and speed that matter when conditions go dark. Whether you're carrying for duty, sport shooting, or hunting across changing daylight, the X-Ray 3 system stays consistent—no swapping between day and night setups.

Tritium illumination is the core of the X-Ray 3 design. The front sight glows green in low light, while the rear sight's blacked-out body and high-contrast profile keep your sight picture sharp and intuitive regardless of ambient light. In daylight, the sights remain bright and white, delivering reliable sight performance across the full spectrum of shooting conditions. The steel construction surrounding each tritium element protects against recoil, solvents, and the wear of field use—this is a design built to work for over a decade.

Installation and compatibility vary by platform, so verify fitment to your specific Sig firearm before purchase. The #6 front sight and #8 round notch rear are sized for standard Sig applications, but confirm your model's requirements. Once mounted, you get a proven night sight system that doesn't demand battery power or constant maintenance—just reliable, self-illuminating performance when you need it.
