The AR-15 and M16 are two of the most recognizable firearms in the world, with a shared history and design roots. However, despite their similarities, these two rifles have distinct differences that set them apart. In this article, we'll explore the 5 key differences between the AR-15 and M16, helping you understand the unique characteristics of each rifle.
Origins and Purpose
To understand the differences between the AR-15 and M16, it's essential to know their origins and purpose. The AR-15 was designed by ArmaLite in the late 1950s as a civilian version of the military's M16 rifle. The M16, on the other hand, was specifically designed for military use, with the first production models being introduced in the early 1960s.
Key Differences
1. Fully Automatic vs Semi-Automatic
One of the most significant differences between the AR-15 and M16 is their firing mode. The M16 is a fully automatic rifle, capable of firing multiple rounds with a single trigger pull. The AR-15, on the other hand, is a semi-automatic rifle, firing only one round per trigger pull.
2. Receiver Design
Upper and Lower Receiver Differences
The receiver design of the AR-15 and M16 differs significantly. The M16 has a fully automatic sear and an auto selector switch, which allows the rifle to fire in fully automatic mode. The AR-15, however, has a semi-automatic sear and no auto selector switch.
3. Gas System
Difference in Gas System Design
The gas system of the AR-15 and M16 is another area where they differ. The M16 has a direct gas system, which directs the hot gases from the barrel directly into the receiver, cycling the action. The AR-15, on the other hand, has a more complex gas system, with a gas block and a gas tube that directs the gases into the receiver.
4. Barrel Design
Barrel Differences: Twist Rate and Length
The barrel design of the AR-15 and M16 also differs. The M16 has a faster twist rate (1:12 inches) and a shorter barrel length (20 inches) compared to the AR-15 (1:9 inches and 24 inches, respectively). This difference in twist rate and barrel length affects the accuracy and range of the two rifles.
5. Accessories and Customization
Accessories and Customization Options
Finally, the AR-15 and M16 differ in terms of accessories and customization options. The AR-15 has a vast aftermarket of accessories and customization options, with countless manufacturers producing a wide range of parts and accessories. The M16, being a military rifle, has more limited customization options, with most accessories being designed specifically for military use.
