Description
FAB Defense FXFBS is a low-profile, flip-up front back-up sight designed to mount on a 1913 Picatinny rail. It uses a spring-locked deployment mechanism and folds down to a smooth, inconspicuous profile that is intended to avoid snagging on gear. The sight pin elevation is adjustable without tools, and the front shroud helps center the image with any rear sight.
