Up for sale is a Knights Armament 14.5 upper, all factory in FDE. Almost new in box with whatever papers or junk it came with. Match that lower you have to this and you'll have a nice factory looking gun. No muzzle devices have been pinned on. Picture has been ripped off the internet but you get the idea. Obviously no lower is included. I know you probably know this already, but I've been surprised at how many people seem to be unaware of the following:
Barrel is under 16" so by law you must attach to an SBR lower or permanently attach a muzzle device long enough to bring barrel length to over 16". All nfa rules apply, yada yada.
