What Does the Button on an AR-15 Do?
The AR-15, a popular semi-automatic rifle, has various features that make it versatile and user-friendly. One of the most notable features is the button located on the lower receiver. This button serves several purposes and understanding its function can greatly enhance your experience with the firearm. Let’s delve into the details of what the button on an AR-15 does.
Function of the Button
The button on an AR-15 is commonly referred to as the “selector switch” or “selector button.” Its primary function is to switch between the different firing modes of the rifle. The selector switch allows you to choose between semi-automatic, full-automatic, and sometimes, a third mode like “safety” or “single-shot.” Here’s a closer look at each mode:
| Firing Mode | Description |
|---|---|
| Semi-Automatic | With the selector switch set to semi-automatic, the rifle will fire one round with each pull of the trigger. This is the most common mode used for hunting, target shooting, and self-defense. |
| Full-Automatic | When the selector switch is set to full-automatic, the rifle will continue to fire rounds as long as the trigger is held down. This mode is typically used by military and law enforcement personnel. |
| Safety | In the safety mode, the rifle will not fire when the trigger is pulled. This mode is used to prevent accidental discharges and is recommended for carrying the firearm. |
It’s important to note that not all AR-15s come with a full-automatic mode. Some models are restricted to semi-automatic only due to legal regulations in certain countries or states.
How to Use the Selector Switch
Using the selector switch on an AR-15 is relatively straightforward. Here’s a step-by-step guide on how to switch between the different modes:
- Locate the selector switch on the lower receiver of the rifle. It is typically located on the left side of the receiver, just above the magazine well.
- With your index finger, press down on the selector switch while simultaneously moving it to the desired firing mode. You will hear a “click” sound indicating that the switch has been successfully changed.
- Check the selector switch to ensure it is in the correct mode. You can do this by looking at the indicator on the switch, which is usually a dot or a symbol that corresponds to the selected mode.
It’s crucial to be familiar with the position of the selector switch and the corresponding firing mode, as incorrect usage can lead to unintended consequences.
Precautions and Safety
When using the selector switch on an AR-15, there are a few precautions and safety measures to keep in mind:
- Always keep the firearm pointed in a safe direction: Never point the rifle at anything you do not intend to shoot. This is a fundamental rule of firearm safety.
- Check the selector switch before handling the firearm: Ensure the selector switch is in the correct mode before handling the rifle, especially if you are not familiar with the firearm.
- Avoid carrying the firearm in the full-automatic mode: Full-automatic fire can be dangerous and is not recommended for civilian use. Always carry the firearm in the semi-automatic or safety mode.
By following these precautions and safety measures, you can ensure a safe and enjoyable experience with your AR-15.
Conclusion
The selector switch on an AR-15 is a crucial feature that allows you to switch between different firing modes. Understanding its function and how to use it properly can greatly enhance your experience with the firearm. Always prioritize safety and follow the necessary precautions when handling the selector switch and the rifle as a whole.
