Meprolight FUBS Flip-Up Backup Sights 2DR/1DF, Black

The Meprolight FUBS (Folding Back-Up Sights) are tritium-enhanced front and rear flip-up sights engineered to serve as secondary aiming references for AR-platform rifles. The set contains two tritium vials in the rear sight and one tritium vial in the front sight to provide self-illuminated reference points in low-light conditions. Constructed from a polymer/metal composite and finished in black, the sights mount to any 1913 Picatinny rail. Elevation and windage can be rapidly adjusted, and the sights fold down to a low-profile position when not in use.
