The Burris AR-F4 FastFire Mount (Burris part no. 410347) is the simplest and most effective way to mount any FastFire sight on an AR flattop. It positions the FastFire at the optimum height so the red dot can co-witness with flip-up sights, giving the shooter a fast primary aiming point with a mechanical backup always in the sight picture. Metal wings protect the lens from impact and unintentional abuse, and a lower compartment stores a spare battery, an open-end wrench, and a Torx wrench so field maintenance never means digging through a range bag. It fits Weaver or Picatinny-style bases on any AR-platform rifle.
