The XS Sights AR-15 tritium flip-up sight with CSAT and stripe is a fast-acquisition backup iron sight system built for serious shooters who need reliable aiming options in any light condition. Constructed from aluminum with stainless steel clamps and hard coat anodized for durability, these sights mount directly to standard 1913 Picatinny rails on your AR platform and lock securely in place when flipped up. Whether you're running a carbine for duty work, tactical training, or home defense, this two-piece set gives you multiple zero options and proven tritium visibility when batteries die or optics fail.
The front sight features an XS Tritium Stripe design: a 0.105" wide post with a vertical tritium stripe and white painted outline that works in daylight, dawn, dusk, and total darkness. The rear sight incorporates the XS CSAT same-plane aperture, offering a 7-yard zero through the large battle aperture, a 100-yard zero via the precision notch, or rapid target acquisition with the flip-up configuration—all while holding zero across transitions. This layered approach lets you match your sight picture to distance and threat without fumbling adjustments.
Built to milspec standards, these sights are engineered for AR-15 shooters who understand that backup iron sights aren't accessories—they're insurance. Rugged, no-battery reliability, and the flexibility to dial in your preferred zero make this system a trusted choice for hunters, competitive shooters, and those who train seriously.

Frequently Asked Questions
Will these sights work on my AR-15?
Yes. These flip-up sights are built to milspec dimensions and attach to any standard 1913 Picatinny rail found on AR-15 platforms. They lock securely in place and flip up when needed.
Can I use these with a red dot or scope?
Absolutely. These are designed as backup iron sights and can coexist with your primary optic. Flip them up when you need them; lay them down when your main sight is in use.
How does the tritium stripe work in darkness?
Tritium is self-illuminating and requires no battery or external light source. The vertical stripe on the front post glows in low-light and night conditions. The white painted outline remains visible in daylight and aids aiming in bright environments.
What distances do these sights zero?
The system offers multiple zeros: the large battle aperture provides a 7-yard zero for close-quarters work; the precision notch delivers a 100-yard zero for distance shooting. The flip-up design lets you transition between these without losing zero.
