Fab Defense released their new polymer back-up sights. The new low-profile sights were designed specifically for the M4/M16/AR-15 rifles and work with all 1913 Picatinny rails. No tools are required for windage adjustments on their rear sights as well as for elevation adjustments on their front sights.
