FBS is an advanced, low-profile, durable, auxiliary front sight. It can be used with any rear sight, but has been designed to provide an extreme optical advantage when paired with the FAB Defense(R) RBS Rear Back-up Sight. Sight pin elevation is easily and quickly adjusted without tools. FBS is readily mounted on any 1913 Picatinny rail, making it ideal for use on M4 / AR-15 / M-16 platforms and on the FAB Defense(R) KPOS.
