The Smith & Wesson M&P 15 is a popular AR-15 platform rifle, appreciated for its reliability and versatility. One common modification is stock removal and replacement, whether for customizing the rifle's feel, adding features, or simply upgrading to a more comfortable or aesthetically pleasing stock. This guide provides a comprehensive overview of M&P 15 stock removal, covering various stock types and offering helpful tips for a smooth and safe process.
Understanding Your M&P 15 Stock
Before you begin, it's crucial to identify the type of stock on your M&P 15. There are several variations, including:
- Fixed Stocks: These are permanently attached to the lower receiver and cannot be easily removed without tools.
- Collapsible Stocks: These stocks feature a mechanism that allows them to fold or collapse to a shorter length.
- Adjustable Stocks: These offer multiple length-of-pull adjustments, providing a customized fit for different shooters.
Knowing your stock type will determine the specific tools and procedure required for removal. Always refer to your firearm's manual for specific instructions, as procedures may vary slightly depending on the model year and specific features.
Tools Required for M&P 15 Stock Removal
The tools needed will vary depending on the stock type, but generally, you'll need:
- Punch (or appropriate tool): A punch is often needed to remove the stock's retaining pins or screws. The size and type of punch will depend on the specific stock and its retention mechanism. Using the wrong punch can damage your firearm.
- Screwdriver (if applicable): Some stocks use screws for attachment, requiring the appropriate screwdriver.
- Hammer (if applicable): A hammer may be needed to gently tap the punch, but avoid excessive force.
- Appropriate sized Allen Wrench: Many collapsible and adjustable stocks use Allen screws or bolts.
- Gunsmithing Mat or Soft Cloth: Protect your firearm's finish during the process.
Step-by-Step Guide to M&P 15 Stock Removal
Safety First: Before undertaking any firearm modification, always ensure the firearm is unloaded and cleared. Double-check by visually inspecting the chamber and magazine well.
The exact steps will vary depending on the type of stock. Here's a general outline:
- Identify the Retention Mechanism: Carefully examine your stock to identify how it's attached to the lower receiver. Look for pins, screws, or other fasteners.
- Prepare Your Workspace: Lay down a gunsmithing mat or soft cloth to protect your rifle from scratches.
- Remove the Stock: Using the appropriate tools (punch, screwdriver, Allen wrench), carefully remove the retaining pins or screws. Apply gentle pressure; avoid excessive force that could damage the receiver or stock. Consult your firearm's manual for detailed instructions.
- Inspect the Receiver: Once the stock is removed, inspect the receiver for any damage or debris.
- Install New Stock (If Applicable): If installing a new stock, follow the manufacturer's instructions carefully.
Troubleshooting Common Issues
- Stuck Pins: If pins are stuck, apply a penetrating oil (like a quality gun oil) and allow it to penetrate for a few minutes before attempting removal. Use gentle tapping with the punch; avoid forceful hammering.
- Stripped Screws: If a screw is stripped, consult a qualified gunsmith for assistance. Attempting to forcefully remove a stripped screw can cause significant damage.
- Damaged Receiver: If you notice any damage to the receiver during the process, immediately stop and seek professional assistance from a qualified gunsmith.
Choosing a Replacement Stock
Selecting a replacement stock depends on your needs and preferences. Consider factors like:
- Length of Pull: The distance between the trigger and the butt of the stock.
- Adjustability: The ability to customize the stock's length and cheek weld.
- Weight: Lighter stocks can reduce fatigue during extended shooting sessions.
- Material: Stocks are available in various materials, including polymer, aluminum, and wood, each with its own pros and cons.
Replacing your M&P 15's stock is a relatively straightforward process, but always prioritize safety and accuracy. If you're uncomfortable performing this task yourself, seek professional help from a qualified gunsmith. Remember to consult your firearm's manual for detailed instructions and safety precautions specific to your model.
