The M16A1 is one of the most ubiquitous and recognizable US small arms to have ever been manufactured. A Eugene Stoner design, the M16 is a select-fire, magazine-fed, lightweight rifle chambered in the small but lethal 5.56.mm NATO cartridge. In early stages of development, the United States Ordnance Department was very resistant to the “futuristic” design of the rifle, preferring the traditional “wood and steel” layout of the M16’s predecessors. However, when Secretary of Defense Robert McNamara laid hands on the rifle, the M16’s adoption into United States service was all but settled. Early versions of the M16 (601, 602, 603, XM16E1) were deployed to Vietnam for testing and evaluation. Through multiple improvements including the addition of a birdcage flash hider, forward assisted and chrome-lined barrel, the M16 and M16A1 were type classified and adopted (M16 going to the Airforce and the M16A1 going to the Army). The M16 would see many revisions through the decades and remains a staple in the US military today.
