Introduction to the M16 Assault Rifle
The M16 is a lightweight, 5.56mm, magazine-fed, gas-operated, air-cooled, selective fire assault rifle that has been in service with the United States military since the 1960s. Designed by ArmaLite, a subsidiary of Fairchild Aircraft, the M16 is a derivative of the earlier AR-15 rifle, with the main difference being the addition of a heavier buffer and a modified bolt carrier group.
Design and Development
The M16 was designed in the late 1950s by ArmaLite’s chief designer, Eugene Stoner, who had previously worked on the AR-15 rifle. The AR-15 was a lightweight, 5.56mm rifle that used a direct gas impingement system to cycle the action. However, the AR-15 had some reliability issues, which were addressed in the M16 design.
The M16 has a few key design features that distinguish it from other assault rifles:
- Modular design: The M16 has a modular design, with the upper and lower receivers being separate components that can be easily interchanged.
- Direct gas impingement system: The M16 uses a direct gas impingement system, where the high-pressure gases from the firing cartridge are used to cycle the action.
- Rotating bolt: The M16 has a rotating bolt that locks into place when the rifle is fired, providing a secure and reliable seal.
Key Features
Some of the key features of the M16 assault rifle include:
- Caliber: 5.56x45mm NATO
- Barrel length: 20 inches (508 mm)
- Overall length: 39.5 inches (1003 mm)
