Meprolight USA FRBS AR-15 Flip-Up Backup Sight Set 2-Dot Orange/Green Tritium - Black

The Meprolight USA FRBS (Flip Back-up Rifle Sights) is a low-profile, tritium-enhanced backup sight set purpose-built for the AR-15 and the broader AR platform. Designed for quick deployment, the rear and front flip up from a folded, snag-free position to deliver reliable mechanical aiming whenever a primary optic fails or when running an iron-sighted setup. The sights lay flat when stowed, keeping the top of the rifle clean when paired with a primary red dot, holographic, or magnified optic.

The set is built around a high-grade polymer and metal housing finished in low-reflective Black and mounts directly to any standard Picatinny rail. This 2-Dot configuration pairs an orange tritium front post with a green tritium rear aperture, giving you self-illuminated visibility day or night without batteries or fiber optics. Both sight assemblies fold flat under spring tension and deploy with a positive click so the shooter can transition from optic to iron aiming quickly and confidently.

Adjustment is quick and intuitive, with 0.50 MOA windage and 1.30 MOA elevation per click so you can zero the set to match your rifle and chosen ammunition. Whether mounted as a primary sighting system or as a redundant back-up on a duty, defensive, or range rifle, the FRBS delivers always-ready tritium illumination and dependable flip-up performance in a lightweight, low-profile package.

Your purchase includes one Meprolight USA FRBS Sight Set consisting of the front sight assembly and rear sight assembly, ready for installation on your AR-platform firearm.
