Meprolight FRBS Flip-Up Sights, AR-15, Orange/Green Tritium

The Meprolight FRBS is a flip-up backup sight set for AR-15 platforms, combining a black polymer and metal construction with tritium-enhanced front and rear sights. The orange tritium front and green tritium rear provide a self-illuminated secondary sighting system for use when primary optics are unavailable.

The sights quickly deploy into position with a spring-locked mechanism. Front sight elevation and rear sight windage can be adjusted without tools, and the set mounts directly to a Picatinny rail without modifications using the provided 2.5mm hex key.
