Meprolight AR-15 Tritium Green Dot Night Sight Front Post$39.99
Availability: In Stock
The Meprolight FRBS flip-up night sight set brings reliable tritium illumination to your AR-15 without the need for batteries or electronic components. Designed as both a primary sighting solution and a robust backup to your optics, this two-piece set combines low-profile mechanics with the durability AR shooters expect. Whether you're running a red dot setup that needs a fallback or building a minimalist setup around iron sights, the FRBS delivers hyper-bright tritium green in a manual, tool-free design that stays on the gun.
Built from fiberglass-reinforced polymer paired with metal construction, the front and rear sights mount to any Picatinny rail and lock down with a spring-based mechanism engineered to withstand hard use without breaking or deforming. The front sight features that signature hyper-bright tritium green, while the rear incorporates a 2-dot configuration for quick target acquisition in low light. Adjust elevation and windage by hand—no specialized tools, no fuss. The minimalist profile keeps your sight picture clean and your rail real estate open for attachments.
Meprolight backs the tritium luminance with a 12-year warranty, a confidence statement from a company that's been building night sights since the 1980s. If you shoot carbine, train at night, or simply want a no-fail aiming system when your optics aren't available, this set earns its spot on your AR.

Yes. The FRBS is designed as both a primary and backup sight system. Many shooters run them alongside a red dot, using the low-profile design to co-witness or deploy the irons when their optic fails or they want a quick return to iron geometry.
No. All adjustments are manual and tool-free. You can zero or dial on the fly at the range without carrying a multi-tool or screwdriver set.
The set includes both the front and rear flip-up sights ready to mount to your Picatinny rail. No additional components are needed for installation on standard AR-15 rifles.
Meprolight warranties the tritium luminance for 12 years. Tritium is self-luminous and doesn't require batteries, so these sights work in complete darkness as long as the tritium is active.
