What does "M" stand for in M16?
The M16 is a popular firearm that has been widely used by the United States military and law enforcement agencies. Despite its widespread use, many people are still unaware of the meaning behind the "M" in M16. In this article, we will explore the origins of the M16 and what the "M" stands for.
Early History of the M16
The M16 was designed in the late 1950s as a replacement for the M14 rifle, which was the standard-issue rifle for the United States military at the time. The M14 was a heavy and bulky rifle that was chambered in 7.62x51mm NATO. The US military was looking for a lighter and more compact rifle that could fire a smaller caliber cartridge. This led to the development of the M16, which was chambered in 5.56x45mm NATO.
The Origins of the M16’s Name
So, what does the "M" stand for in M16? The "M" in M16 stands for Military, not as many people assume, "Masterpiece" or "Magnum". The term "M16" is a designation given by the US military to the rifle, and it is short for "US Rifle, 5.56mm, M16". The "M" in M16 is not an abbreviation, but rather a designation that indicates that the rifle is a standard-issue weapon for the military.
Other Designations in the M16
The M16 is often referred to as the AR-15, which stands for ArmaLite Rifle-15. ArmaLite was a company that developed the original design of the M16, and the AR-15 was the civilian version of the rifle. Over time, the term "AR-15" has become synonymous with the M16, and many people use the terms interchangeably.
