Knights Armament KAC M4 front micro flip-up BUIS

Often featured as standard equipment on Knights SR15 and SR25 rifles, these are solid folding front back up sights

This Micro M4 sight fits on a 1913 Picatinny Rail.  KAC’s line of Micro Iron Sights are currently in use by the United States Army, Marine Corps, and numerous law enforcement agencies worldwide. This is because they are built to exacting tolerances, maintain their zero under adverse conditions, and when folded have one of the lowest profile top-rail foot prints in the industry. Our Folding Micro Front Sight is no exception and features a tool-free, finger-adjustable front sight post that makes performing sight corrections extremely fast and simple.  

The Micro M4 flip-up front sight is a great addition to your military clone build, or to any rifle looking for a solid, affordable and well performing back up iron sight.  Knights sights are known for showing a little wear, as they are constructed of the finest steels and aluminums and their finish can be little uneven.  If you are looking for a museum piece, this is probably not your first choice.  If you are looking for battle proven reputation that will last a lifetime, maybe you should step up to KAC.
