The AR-15 platform, while incredibly popular, demands respect and a thorough understanding of its safety mechanisms. Improper handling can lead to serious injury or even death. This guide focuses on the installation and proper understanding of the AR-15 safety selector, a critical component for safe firearm operation. We’ll delve into the mechanics, different types, and troubleshooting common issues.
Understanding the AR-15 Safety Selector
The AR-15 safety selector is a lever, typically located on the receiver behind the trigger, that controls the firearm’s ability to fire. It usually features three positions:
- Safe (S): The firearm is completely locked; the hammer cannot fall, preventing accidental discharge. This is the most crucial position when not actively shooting.
- Semi-Automatic (Semi or S): The firearm will fire one round per trigger pull. This is the standard firing mode for most applications.
- Automatic (Auto or F - sometimes): This position is only found on select models (not standard AR-15s) and allows for fully automatic fire—meaning continuous firing as long as the trigger is depressed. This mode is highly regulated and often restricted by law.
Note: The markings (S, Semi, Auto) and their positions can vary slightly depending on the manufacturer. Always consult your firearm's manual for specific details.
Types of AR-15 Safeties
Several types of safety selectors exist, each offering slightly different functionalities and ergonomics:
- Standard Ambidextrous Safety: Features levers on both sides of the receiver, allowing for easy manipulation by both left- and right-handed shooters.
- Enhanced Ambidextrous Safety: Often feature larger, more easily manipulated levers for quicker and more positive engagement.
- Non-Ambidextrous Safety: Only has a lever on one side of the receiver, typically the right side.
Installing an AR-15 Safety Selector
Installing a new safety selector usually involves a relatively straightforward process, but it's crucial to exercise caution and follow the correct steps. Improper installation can render the safety mechanism ineffective, compromising firearm safety. The process typically involves:
- Disassembly: Safely disassemble the lower receiver. This requires familiarity with AR-15 disassembly procedures. Always ensure the firearm is unloaded and clear before beginning any disassembly or maintenance.
- Removal of the old selector: Using a punch or similar tool, carefully remove the existing safety selector pins.
- Installation of the new selector: Insert the new safety selector into place, ensuring it aligns correctly.
- Reassembly: Reinsert the selector pins, ensuring they are fully seated.
- Function check: Carefully test the safety selector's functionality, confirming it engages properly in all positions (Safe, Semi, Auto, if applicable).
Troubleshooting
If your safety selector doesn't function correctly after installation, consider the following:
- Improper Installation: Double-check that the selector is correctly aligned and the pins are fully seated.
- Damaged Parts: Examine the safety selector and its surrounding parts for any damage or wear.
- Incorrect Selector: Verify you have the correct replacement part for your specific AR-15 model.
Safety First: A Final Word
This guide provides a general overview of AR-15 safety selectors. Remember that working with firearms requires responsibility and caution. Always consult your firearm's manual, and if unsure about any aspect of maintenance or repair, seek professional assistance from a qualified gunsmith. Improper handling of firearms can have devastating consequences. Prioritize safety above all else.
