The XS Sights Steel Matte Tritium Front Night Sight Post for AR-15 is a precision-machined front sight replacement built to keep your target picture clear whether you're shooting in bright daylight or low-light conditions. This steel post features a tritium vial that glows independently of external light sources, paired with a white outline that enhances visibility across the entire lighting spectrum. If you run iron sights on your AR platform—whether for backup, hunting, or dedicated iron-sight competition—this front sight post delivers the dependable aiming reference serious shooters need.
XS designed this sight around practical shooting fundamentals. The 0.105" square top post geometry is proven on the range, and the stress-proof steel construction is machined to exacting tolerances so your zero stays solid through hard use. Installation is straightforward: it fits AR-15 front sight housings with detent positions at 3, 6, or 9 o'clock, giving you flexibility in mounting. Elevation adjustments are intuitive—each full rotation of the front sight delivers a 5" point-of-impact shift at 100 yards, so dialing in your load or distance is incremental and predictable. All of that is built right here in the USA.
Whether you're setting up a truck gun, a hunting rifle, or a range toy, a quality tritium front post is one of the best upgrades you can make to aging AR furniture. XS Sights' no-frills approach means you get a sight that works, not marketing fluff—and the tritium vial earns its keep the moment you need it.

Frequently Asked Questions
Will this front sight fit my AR-15?
Yes, it's designed for standard AR-15 front sight housings. The detent can be positioned at 3, 6, or 9 o'clock to match your specific housing configuration.
What does the tritium do, and why do I need it?
The tritium vial glows on its own—no batteries or light required—making your sight visible in darkness, dawn, dusk, or other low-light scenarios. The white outline provides aiming reference in daylight. Together, they cover you across all lighting conditions without changing sights.
How do I adjust elevation on this sight?
Each complete rotation of the front sight post moves your point of impact 5 inches at 100 yards, allowing precise, incremental adjustments for zeroing different loads or distances.
Is this an upgrade over factory AR sights?
This is a replacement front sight post for AR platforms equipped with standard front sight housing. If you're running older, unmarked factory iron sights or need a tritium upgrade to an existing sight, this post delivers the night-light capability and precise machining that quality aftermarket sights offer.
