Visual Difference Between Semi and Full Auto AR-15
The AR-15 is one of the most popular firearms in the United States, and it comes in various configurations, including semi-automatic and fully automatic. While both types of AR-15s share the same basic design, there are several visual differences that set them apart. In this article, we will explore the visual differences between semi and full auto AR-15s to help you identify the key distinctions between the two.
First and foremost, the most noticeable visual difference between a semi-automatic and a fully automatic AR-15 is the rate of fire. Semi-automatic AR-15s fire one round with each pull of the trigger, while fully automatic AR-15s can fire multiple rounds rapidly with a single pull of the trigger. This difference is evident in the design of the selector switch, which is the control that allows the shooter to switch between semi-automatic and fully automatic modes.
In a semi-automatic AR-15, the selector switch is typically located on the left side of the firearm, just above the magazine well. It features two positions: “S” for semi-automatic and “F” for fully automatic. When the selector switch is set to “S,” the firearm will fire one round per trigger pull. When set to “F,” the firearm will fire multiple rounds rapidly, depending on the rate of fire allowed by the firearm’s design and the shooter’s skill.
On the other hand, a fully automatic AR-15 will have a different selector switch design. The selector switch on a fully automatic AR-15 is often larger and more prominent, as it needs to accommodate the complex mechanisms required for full automatic fire. Fully automatic AR-15s may also have a distinctive “burst” fire mode, which allows the firearm to fire a set number of rounds (usually three) rapidly before pausing for a short period.
Another visual difference between semi and full auto AR-15s is the presence of a barrel shroud. A barrel shroud is a metal or polymer cover that encloses the barrel and helps to dissipate heat. Semi-automatic AR-15s typically have a barrel shroud, while fully automatic AR-15s may not. This is because the rapid firing of a fully automatic firearm generates more heat, which can damage the barrel shroud.
Additionally, the sights on a semi-automatic and a fully automatic AR-15 may differ. Semi-automatic AR-15s usually come with standard iron sights, while fully automatic AR-15s may have more advanced sights, such as holographic or red dot sights, to help the shooter maintain accuracy during rapid fire.
In conclusion, the visual differences between semi and full auto AR-15s are evident in the selector switch design, barrel shroud, and sights. While both types of firearms share the same basic design, these visual distinctions make it easy to identify the key differences between the two. Whether you’re a firearms enthusiast or a law enforcement officer, understanding these differences can help you make informed decisions about the type of AR-15 that best suits your needs.
