For AR and carbine shooters Burris bundles a 3 MOA FastFire III with the rugged AR-F3 mount. It\u2019s the simplest and most effective way to mount any FastFire on an AR flattop as a stand-alone sight or as a co-witness for iron sights. The FastFire sits low in the mount and a pair of metal wings on each side of the lenses protects the sight from impact or unintentional abuse. For added convenience a lower compartment offers storage for a spare battery open-end wrench and Torx\u00ae wrench. Fits any Weaver or Picatinny-style base.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
