The history of the M16 did not start off well when it was first deployed and issued to ground troops in the Vietnam War. For all the testing that was performed on this weapon, as it turns out, it was not the fault of the designer, Colt Firearms, nor was it a bad rifle, but the blame for it's poor performance was the U.S. Army itself. The earliest versions of this rifle were identifiable by the 3 prong muzzle flash suppressor at the end of the barrel. The newer models had a fully enclosed suppressor.
