The AR-15 platform's modularity is a significant part of its appeal. One popular modification is the side charging handle, offering benefits for shooters in certain situations. However, like any part, it might eventually need replacing. This guide provides a comprehensive walkthrough of replacing your AR-15 side charging handle, covering various aspects from choosing the right replacement to the installation process itself.
Why Replace Your AR-15 Side Charging Handle?
Several reasons might prompt you to replace your side charging handle:
- Wear and Tear: Like any mechanical component, repeated use can lead to wear and tear. This can manifest as increased friction, stiffness, or even failure to function correctly.
- Damage: Accidental drops, impacts, or improper handling can damage the charging handle, rendering it unusable.
- Upgrade: You might want to upgrade to a higher-quality charging handle made from a more durable material (like steel) or one with improved ergonomics. Some users prefer ambidextrous charging handles for increased versatility.
- Customization: Aesthetics play a role for many AR-15 owners. Replacing the charging handle allows customization to match the overall look and feel of the rifle.
Choosing the Right Replacement Charging Handle
Before starting the replacement process, selecting the correct side charging handle is crucial. Consider these factors:
- Compatibility: Ensure the new charging handle is compatible with your specific AR-15 upper receiver. Some side charging handles are designed for specific brands or models. Check manufacturer specifications carefully.
- Material: Charging handles are typically made from aluminum, steel, or polymer. Steel offers superior durability, while aluminum provides a good balance of strength and weight. Polymer is the lightest option but may not be as durable under heavy use.
- Ambidextrous vs. Right-Side Only: Ambidextrous charging handles offer the ability to operate the charging handle from either side, which can be beneficial for left-handed shooters or those using accessories that might obstruct the standard charging handle location.
- Size and Ergonomics: Consider the size and shape of the charging handle. A larger handle might provide better grip, but it could also interfere with optics or other accessories.
Step-by-Step Replacement Guide
Tools Required:
- Punches (small and medium)
- Hammer
- Torque wrench (optional, but recommended)
- Possibly a roll pin starter
Steps:
-
Disassemble the Upper Receiver: Carefully remove the upper receiver from the lower receiver. Ensure the firearm is unloaded and clear of any ammunition.
-
Remove the Old Charging Handle: Locate the roll pin(s) securing the charging handle to the upper receiver. Using a small punch and hammer, gently tap out the roll pin(s) from the receiver. Be careful not to damage the receiver or the charging handle.
-
Install the New Charging Handle: Carefully align the new charging handle with the upper receiver. Insert the roll pin(s) through the charging handle and receiver. If using a roll pin starter tool, this will help to avoid damaging the receiver or roll pin. If not, start the pin using the punch carefully.
-
Tap in the Roll Pins: Use a hammer and a medium-sized punch to gently tap the roll pin(s) fully into the receiver until they are flush. Avoid hammering too hard, as this can damage the roll pin or the receiver.
-
Reassemble the Upper and Lower Receivers: Once the new charging handle is securely installed, reassemble the upper and lower receivers.
-
Test the Function: Cycle the charging handle several times to ensure it operates smoothly and functions correctly.
Safety Precautions
- Always handle firearms safely. Ensure the firearm is unloaded before performing any maintenance or modifications.
- Wear eye protection to prevent injury from flying debris.
- Use the correct tools. Using the wrong tools can damage your firearm or cause injury.
- Take your time. Rushing the process can lead to errors and potentially damage your firearm.
Conclusion
Replacing an AR-15 side charging handle is a relatively straightforward process, but it's crucial to take your time and follow the steps carefully. By choosing the right replacement and following these instructions, you can ensure your AR-15 remains in top working condition. Remember to prioritize safety throughout the entire process. If you're uncomfortable performing this task yourself, consult a qualified gunsmith.
