FAB Defense FRBS Offset Folding Rifle Sights Kit, Tan

The FAB Defense FRBS Offset Folding Sights Kit (FAB Defense part no. fx-frbsost) gives rifle shooters a back-up sighting solution built to work alongside a magnified optic in close-quarters scenarios. FAB Defense designed the kit around a low-profile, minimal-footprint build so the folded sights stay out of the way until you need a fast, offset sight picture. The rear back-up sight adjusts for windage and the front back-up sight adjusts for elevation, both without tools, and the kit mounts directly to any standard 1913 MIL-STD picatinny rail. Finished in tan and built from fiberglass-reinforced polymer and metal, it holds up to hard use while staying light on the gun.
