Burris AR-F3 Fastfire III w/ AR Mount

  • For AR and carbine shooters, the AR-F3 combines the FastFire III sight with the rugged AR-F3  mount.

    It’s the simplest and most effective way to mount any FastFire sight on an AR flattop as a standalone sight or as a co-witness for iron sights.

    The FastFire sits low in the mount. Metal wings on each side of the lens protect the sight from impact or unintentional abuse.

    A lower compartment offers convenient storage for a spare battery, open-end wrench, and Torx® wrench (all sold seperately). Fits any Weaver or Picatinny-style base.

    The AR-F3 is a versatile lightweight optics solution for practical AR enthusiasts.
