Understanding the AR-15 Full Auto Selector Switch: A Comprehensive Guide
The AR-15 full auto selector switch is a crucial component of the AR-15 rifle, allowing users to switch between semi-automatic and fully automatic firing modes. In this detailed guide, we will explore the various aspects of the full auto selector switch, including its design, functionality, and the importance of using it responsibly.
Design and Construction
The AR-15 full auto selector switch is typically made of durable materials such as aluminum or steel, ensuring its longevity and resistance to wear and tear. The switch is designed to be easily accessible, allowing users to quickly change firing modes without compromising their grip on the rifle.
One of the key features of the full auto selector switch is its three-position design. The switch is usually marked with “S” for semi-automatic, “A” for automatic, and “S” again to indicate the semi-automatic position. This design ensures that users can easily identify the current firing mode at a glance.
Functionality
The AR-15 full auto selector switch operates by engaging or disengaging the rifle’s fire control group. When the switch is set to semi-automatic, the rifle will fire one round with each trigger pull. When the switch is set to automatic, the rifle will continue to fire rounds as long as the trigger is held down.
It is important to note that the full auto selector switch is not a trigger. Instead, it controls the rifle’s fire control group, which includes the bolt carrier group, the hammer, and the sear. When the switch is set to automatic, the hammer will continue to strike the firing pin, causing the bolt carrier group to cycle and fire rounds until the magazine is empty or the trigger is released.
Importance of Responsible Use
While the full auto selector switch offers the excitement and thrill of fully automatic fire, it is crucial to use it responsibly. Fully automatic firearms are highly regulated in many countries, and their use is often restricted to military, law enforcement, and certain civilian applications.
Here are some key points to consider when using the AR-15 full auto selector switch:
-
Always ensure that the rifle is unloaded and the chamber is clear before changing firing modes.
-
Never point the rifle at anything you do not intend to shoot.
-
Use full auto fire only in designated areas and under the supervision of a qualified instructor.
-
Be aware of local laws and regulations regarding the use of fully automatic firearms.
Types of Full Auto Selector Switches
There are several types of full auto selector switches available for the AR-15 rifle. Some of the most common types include:
| Type | Description |
|---|---|
| Standard | Standard full auto selector switches are designed for use with mil-spec fire control groups and are compatible with most AR-15 rifles. |
| Short Stroke | Short stroke full auto selector switches are designed for use with carbine-length fire control groups and offer a shorter throw, making them easier to manipulate. |
| Long Stroke | Long stroke full auto selector switches are designed for use with full-length fire control groups and offer a longer throw, providing more leverage for users with larger hands. |
Installation and Maintenance
Installing a full auto selector switch on an AR-15 rifle is a relatively straightforward process, but it is important to follow the manufacturer’s instructions carefully. Here are some general steps to consider:
-
Disassemble the rifle and remove the fire control group.
-
Install the new full auto selector switch onto the fire control group, ensuring that it is properly aligned.
-
Reassemble the rifle and test the new switch to ensure it operates correctly.
Regular maintenance of the full auto selector switch is also important to ensure its proper functioning. This includes cleaning the switch and the surrounding area, as well as inspecting for any signs of wear or damage.
Conclusion
The AR-15 full auto selector switch is a fascinating component that adds a unique
