What is the Button on the Side of an AR-15?
When you pick up an AR-15, one of the first things you might notice is a button on the side of the receiver. This button is not just a mere accessory; it serves a crucial purpose in the functionality of the firearm. In this article, we will delve into the details of this button, its uses, and its importance in the AR-15 platform.
Understanding the Location
The button is typically located on the left side of the receiver, near the magazine well. It is usually situated above the magazine release button, making it easily accessible with your thumb while holding the firearm.
Functionality of the Button
The button on the side of an AR-15 is commonly referred to as the “selector switch.” Its primary function is to toggle between the different modes of fire: semi-automatic, three-round burst, and fully automatic. Let’s take a closer look at each mode:
| Mode of Fire | Description |
|---|---|
| Semi-Automatic | In this mode, the firearm fires one round with each trigger pull. It is the most common mode used for hunting, target shooting, and self-defense. |
| Three-Round Burst | This mode allows the firearm to fire three rounds consecutively with each trigger pull. It is often used in military and law enforcement applications where controlled bursts are preferred. |
| Full Automatic | In full automatic mode, the firearm continues to fire rounds as long as the trigger is held. This mode is typically reserved for military use and is illegal for civilian ownership in many countries. |
Operating the Selector Switch
Operating the selector switch is a straightforward process. To change the mode of fire, simply press the button with your thumb while holding the firearm. The selector switch will move to the desired position, and you will hear a “click” sound indicating that the mode has been changed. It is essential to ensure that the selector switch is in the correct position before firing the firearm to avoid unintended consequences.
Importance of the Selector Switch
The selector switch is a critical component of the AR-15 platform. It allows the user to choose the appropriate mode of fire for different situations. For example, in a self-defense scenario, you may want to use semi-automatic mode for controlled shooting. In a combat environment, three-round burst mode can provide a balance between rapid fire and controlled bursts. The selector switch gives the user the flexibility to adapt to various situations.
Common Questions About the Selector Switch
Here are some frequently asked questions about the selector switch on an AR-15:
- Can I change the selector switch myself? Yes, you can change the selector switch on your AR-15. However, it is recommended to have it done by a professional to ensure proper installation and functionality.
- Can I install a different type of selector switch? Yes, you can install different types of selector switches, such as ambidextrous switches or switches with different colors. However, it is essential to ensure that the new switch is compatible with your firearm.
- Is it legal to have a full automatic selector switch? The legality of full automatic selector switches varies by country and sometimes by state. It is crucial to check the laws in your area before purchasing or installing a full automatic selector switch.
Conclusion
The button on the side of an AR-15, known as the selector switch, is a crucial component that allows the user to choose the appropriate mode of fire for different situations. Understanding its functionality and importance can help you make the most of your firearm and ensure safe and effective use.
