The Smith & Wesson M&P 15-22 is a popular .22LR rimfire rifle, appreciated for its affordability and reliability as a training tool or plinking gun. However, like any firearm, parts can wear out or break, and the charging handle is no exception. This guide provides a step-by-step walkthrough on how to replace your M&P 15-22 charging handle, ensuring you can get back to the range quickly and safely. We'll cover choosing the right replacement, the tools you'll need, and the process itself.
Understanding Your M&P 15-22 Charging Handle
Before diving into the replacement, let's understand the charging handle's role. The charging handle is the lever you pull to cycle the action, loading a fresh round into the chamber. A broken or malfunctioning charging handle will render your rifle inoperable. Common reasons for replacement include:
- Broken Latch: The small latch that holds the charging handle in place can break due to wear and tear or forceful manipulation.
- Bent Handle: Dropping the rifle or other impacts can bend the charging handle, making it difficult or impossible to operate.
- Wear and Tear: Over time, the charging handle can develop wear that affects its smooth operation.
- Upgrade: Some shooters choose to replace the stock charging handle with an aftermarket option for enhanced ergonomics or aesthetics.
Knowing why your charging handle needs replacing helps determine the type of replacement you need.
Choosing the Right Replacement Charging Handle
The market offers various M&P 15-22 charging handles, ranging from factory replacements to aftermarket options. When choosing, consider:
- Material: Most are made of steel or polymer. Steel is more durable but heavier, while polymer is lighter but might be less resilient to damage.
- Ambidextrous Design: Some charging handles are ambidextrous, allowing for easier operation by both left and right-handed shooters.
- Size and Shape: Aftermarket handles may offer different sizes and shapes for enhanced grip and comfort.
- Manufacturer Reputation: Choose reputable manufacturers known for quality and reliability.
Important Note: Ensure your replacement charging handle is specifically designed for the Smith & Wesson M&P 15-22. Using an incorrect part can lead to malfunctions or damage.
Tools and Materials Needed
Before starting the replacement, gather the following:
- New M&P 15-22 Charging Handle: The correct replacement part.
- Small Flathead Screwdriver: For removing the takedown pins.
- Punch (optional but recommended): A small punch can help prevent damage to the takedown pins.
- Clean Work Surface: To prevent losing small parts.
- Gun Cleaning Mat (optional): To protect the firearm's finish.
Step-by-Step Replacement Process
Safety First: Always treat your firearm as if it were loaded. Before beginning any work, ensure the firearm is unloaded and the magazine is removed. Visually inspect the chamber to confirm it's empty.
-
Field Strip the Rifle: Follow Smith & Wesson's instructions for field stripping the M&P 15-22. This usually involves removing the bolt carrier group (BCG) which includes the charging handle. Consult your firearm's manual for detailed instructions. Improper field stripping can damage the firearm.

Reassemble the Rifle: Reverse the field stripping process, carefully reinstalling all components.
-
Function Check: Once reassembled, visually inspect for proper function and perform a function check with dummy rounds. Never use live ammunition during a function check.
Troubleshooting
If you encounter problems during the replacement, consider these troubleshooting steps:
- Double-check the Alignment: Ensure the new charging handle is correctly aligned with the BCG.
- Check for Obstructions: Make sure there are no obstructions preventing smooth operation.
- Consult the Manufacturer: If you're still having issues, contact the manufacturer of the replacement charging handle for assistance.
