Installing an AR-15 trigger guard might seem daunting, but with the right tools and a little patience, it's a straightforward process even for beginner gunsmiths. This guide provides a comprehensive, step-by-step walkthrough, ensuring a smooth and successful installation. We'll cover various types of trigger guards and address common issues you might encounter.
Tools You'll Need
Before you begin, gather the necessary tools:
- New AR-15 Trigger Guard: Ensure you have the correct trigger guard for your lower receiver. Different manufacturers may have slight variations.
- Punch (small diameter): A hardened steel punch is crucial for safely removing the existing trigger guard pin. Avoid using anything that could damage the pin or receiver.
- Hammer: A standard ball-peen hammer will work fine. Use gentle taps to avoid marring the metal.
- Small flathead screwdriver (optional): This might be helpful for gently prying out the trigger guard if it's stubborn.
- AR-15 Lower Receiver: Obviously, you'll need the lower receiver!
- Safety Glasses: Always protect your eyes when working with tools and firearms.
Step-by-Step Installation Process
1. Safety First: Always ensure your firearm is unloaded and the action is clear. Double-check!
2. Removing the Old Trigger Guard (if applicable):
- Locate the Trigger Guard Pin: The trigger guard pin is typically located at the front of the trigger guard, connecting it to the lower receiver.
- Drive Out the Pin: Using your punch and hammer, carefully tap the pin out from the receiver. Start with light taps, working your way to slightly firmer taps as needed. Ensure the pin is fully removed from both sides.
- Remove the Trigger Guard: Once the pin is removed, the trigger guard should slide out easily. If it's stuck, gently use a small flathead screwdriver to pry it free, being careful not to scratch the receiver.
3. Installing the New Trigger Guard:
- Insert the New Trigger Guard: Align the new trigger guard with the receiver and carefully slide it into place. Ensure it fits snugly.
- Insert the Trigger Guard Pin: Align the trigger guard pin with the holes in the receiver and the trigger guard.
- Tap in the Pin: Using your punch and hammer, gently tap the pin back into place. Again, start with light taps and increase pressure gradually until it's fully seated.
4. Final Check:
- Inspect the Installation: Once the pin is fully seated, inspect the trigger guard to ensure it's securely in place and there's no play or looseness.
- Function Check: With an unloaded firearm, perform a function check to make sure the trigger operates smoothly.
Troubleshooting Common Issues
- Pin Won't Go In: Check for obstructions. Ensure the trigger guard is properly aligned with the receiver. If the pin is slightly bent, try straightening it carefully.
- Trigger Guard is Loose: The pin may not be fully seated. Double-check and re-seat the pin.
- Damaged Pin: If the pin is damaged or bent beyond repair, replace it with a new one.
Different Types of AR-15 Trigger Guards
There are several types of AR-15 trigger guards available, including standard, oversized, and ambidextrous options. The installation process remains largely the same regardless of the type. Oversized guards offer more room for gloved hands, while ambidextrous guards provide easier access for both left- and right-handed shooters. Choose the type that best suits your needs and preferences.
Conclusion
Installing an AR-15 trigger guard is a relatively simple process that any gun owner with basic mechanical skills can accomplish. Remember always to prioritize safety and proceed carefully. By following this step-by-step guide and paying attention to detail, you can ensure a successful installation and enjoy your upgraded AR-15. If you encounter significant difficulties, seeking assistance from a qualified gunsmith is always recommended.
