Trinity Force FS72 QF B.U,S. Set AR-15 Black Hard Coat Anodzied Aluminum/Steel

Trinity Force's QF B.U.S. (Back Up Sight) can be used as both a back up sighting system or as a primary sighting system. The AR15 A2 flip-up front sight post folds down out of view of your optics when not in use and is fully adjustable for elevation. The AR15 flip-up rear sight mounts onto the AR15 flat-top receiver, directly onto the Picatinny rail. These sights are equipped with an internal quick-deploy mechanism that can be activated by pressing the body of the sight forward along the axis of gun. This pair of sights are constructed of an aircraft grade aluminum and a high strength steel with a black hard coat anodzied finish.
