Tan FAB Defense backup sights for 1913 Picatinny rails, pairing tool-free rear windage and front elevation adjustment in a low-profile folding kit.
The FAB Defense Front and Rear Backup Sight set in tan is the FRBS kit: the FBS front unit and RBS rear unit supplied as a matched pair rather than bought separately. Both clamp to any MIL-STD-1913 Picatinny rail and both adjust by hand, windage at the rear and elevation at the front, so zeroing needs nothing beyond your fingers.
One fitment point worth noting before you order. The front sight is designed to sit on handguard rail, on the same plane as the rear, not on a railed gas block. Put it on a gas block and the post sits too high to line up. On a straight pull AR or a rimfire AR pattern rifle with a continuous top rail that is rarely a problem, but check the rail runs unbroken first.

Yes, provided the firearm has a standard 1913 Picatinny rail with suitable space for both units. One important exception: the front sight must not be mounted on a railed gas block. Check the rail layout before fitting.
The rear sight provides manual windage adjustment, while the front sight provides manual elevation adjustment. Both can be adjusted without separate tools, making routine zeroing more straightforward.
