Who This Is For
The XS Tritium Stripe AR Mil-Spec sight set is ideal for AR-15 owners who demand reliable, always-ready iron sights for home defense, duty use, or tactical training.

Frequently Asked Questions
Will these sights fit my standard AR-15 or M16-pattern rifle?
Yes. The XS Tritium Stripe AR Mil-Spec sights are designed to fit standard mil-spec AR-15 and M16 front sight bases. They are compatible with the vast majority of AR-platform rifles produced to mil-spec dimensions. If your rifle uses a non-standard or low-profile gas block without a front sight tower, these sights will not be compatible without an appropriate adapter or sight base replacement.
How long does the tritium illumination last?
Tritium has a half-life of approximately 12 years, meaning the glow will gradually dim over time. XS Sights tritium vials are rated to remain usefully bright for approximately 12 years under normal conditions. After that point, the sights remain fully functional as standard iron sights — only the self-luminous glow diminishes. Most manufacturers, including XS Sights, offer tritium replacement services when brightness becomes a concern.
How do XS Stripe sights differ from traditional AR iron sights?
Traditional AR iron sights require a precise, three-part sight picture aligning the front post within a rear aperture — a process that demands focused attention under stress. XS Stripe sights simplify this by pairing a glowing tritium front post with a bold, high-contrast white vertical stripe on the rear sight. This allows the shooter to instinctively align sights faster by "stacking" the front dot on the rear stripe, making them especially effective in dynamic defensive or duty situations where speed is prioritized over benchrest precision.
