Front And Rear Backup Sight Tan

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.
