Burris 410348 AR-F3 Mount AR Platform Black Matte

Burris' AR-F3 is the simplest, most effective way to mount any FastFire sight on an AR flattop. It also allows the FastFire to mount be at the optimum height, so the red dot can co-witness with flip-up sights. The metal wings protect the lens and the lower compartment stores spare battery, open-end wrench and a Torx wrench.
