Meprolight AR-15 Tritium Green Dot Night Sight Front Post

The Meprolight AR-15 Tritium Green Dot Night Sight Front Post is a self-illuminating replacement front sight designed for AR-15 platforms that need reliable low-light aiming capability without batteries or electronic activation. Meprolight's tritium insert glows continuously in darkness, making target acquisition possible in dim conditions—from predawn hunting to indoor ranges to defensive scenarios. This front post drops into your factory AR-15 sight body without any permanent modification or gunsmithing, and Meprolight guarantees the tritium brightness for five years, giving you years of dependable performance.

If you're running an AR-15 and want simple, rugged backup iron sights or a primary aiming solution that doesn't rely on electronics, tritium night sights close the gap between daylight precision and low-light utility. The green tritium glow is easier on the eye than traditional red and works well with modern optics-first setups when you need to transition quickly or co-witness with a mounted red dot or scope.

Installation is straightforward—the front post fits into the standard AR-15 front sight assembly. No drilling, tapping, or fitting required. If you're upgrading a stock rifle or building a complete AR from a parts kit, Meprolight sights give you factory-compatible, field-proven aiming technology without complications.

Frequently Asked Questions

Will this front sight work with my standard AR-15?

Yes. The Meprolight front post is designed to fit directly into factory AR-15 sight bodies without modification. If your rifle has the standard front sight assembly, this is a straightforward swap.

How long does the tritium glow last?

Meprolight guarantees tritium brightness for five years. After that, the sight will continue to function, but the nighttime glow will gradually dim over time.

Can I use this with a red dot or scope mounted on top?

Yes. Tritium front and rear iron sights work well as backup sights or co-witness references alongside modern optics. The green tritium is visible in low light without interfering with your primary sight picture.

Do I need a gunsmith to install this?

No. The Meprolight front post is a drop-in replacement for the factory sight post. Installation requires no permanent modification, gunsmithing, or special tools—just basic familiarity with AR-15 takedown.
