If you're taking a trip to the range or operating in the field you need precise accuracy to hit your targets. Get the optical advantage with these FAB Defense Front & Rear Flip-Up Sight. The FBS and RBS have a low folded profile and is smooth and inconspicuous, and will not snag on gear, webbing, or brush. These sights have an instant spring-locked deployment mechanism that will not slip, break or deform. When they are paired together it creates a precise optical tunnel that ensures more accurate aiming and faster target acquisition.
