Knights Armament 5.56mm SR-15 KS-3, 11.5″-Upper Receiver Kit

Knight's Armament has been quietly setting the standard for the AR platform since Reed Knight started building in Florida - the SR-15 and SR-25, URX rails, folding micro sights and the NT4 and QDC suppressor systems that a good deal of the military inventory runs on. Gallenson's carries KAC rifles, rails, sights, suppressors and mounts in Salt Lake City.
