Removing the handguard on your Smith & Wesson M&P15 can seem daunting, but with the right tools and a methodical approach, it's a straightforward process. This guide will walk you through the steps, covering various M&P15 models and addressing common issues. Whether you're upgrading your handguard, performing maintenance, or troubleshooting a problem, this detailed walkthrough will ensure a smooth and safe removal.
Understanding Your M&P15 Handguard
Before you begin, it's crucial to identify the type of handguard your M&P15 has. Smith & Wesson uses different handguard systems across its M&P15 variants. The most common types include:
- Standard Delta Ring System: This older system utilizes a delta ring and a retaining pin to secure the handguard. Removal typically involves pushing out the retaining pin and carefully maneuvering the handguard off.
- Low-Profile Gas Block System: Often found on newer models, this system features a low-profile gas block integrated into the handguard. Removal may require specialized tools and a more careful approach.
- Free-Floating Handguards: These handguards are not directly attached to the barrel nut, providing greater accuracy and stability. Removal procedures can vary significantly depending on the manufacturer and attachment method.
Tools You'll Need
The specific tools you need will depend on your M&P15's handguard system, but generally, you'll need:
- Punch: A properly sized punch (often a 1/8" or 5/32" punch) for removing the retaining pin (if applicable). Avoid using anything that could damage the pin or your firearm.
- Mallet or Hammer: A soft mallet is recommended to prevent damage to the firearm. A hammer can be used, but extreme caution must be exercised to avoid marring the metal.
- Upper Receiver Vise Block (Recommended): This is crucial for stabilizing the upper receiver during the process and preventing accidental damage.
- Appropriate Wrenches: Depending on your handguard's attachment method, you may need wrenches to loosen or remove barrel nuts or other fasteners.
- Gloves: Protect your hands and prevent accidental scratches on the firearm.
- Clean Work Surface: A clean, well-lit work area is essential for efficient and safe disassembly.
Step-by-Step Handguard Removal (Delta Ring System)
This section outlines the process for removing a handguard secured by a delta ring and retaining pin. Remember to always prioritize safety.
- Secure the Upper Receiver: Place your upper receiver in a vise block to secure it firmly. This prevents accidental movement and damage during the removal process.
- Locate the Retaining Pin: Identify the small retaining pin located on the delta ring. It's usually near the end of the handguard closest to the gas block.
- Remove the Retaining Pin: Use your punch to gently tap the retaining pin out. Start with light taps and increase force only if necessary. Work carefully to avoid bending or damaging the pin.
- Remove the Delta Ring: Once the pin is removed, the delta ring should be loose enough to slide off. Gently work the delta ring off the barrel nut.
- Slide off the Handguard: With the retaining pin and delta ring removed, carefully slide the handguard forward and off the barrel nut.
Step-by-Step Handguard Removal (Other Systems)
For low-profile gas block systems and free-floating handguards, the removal process varies significantly. Consult your firearm's manual or seek guidance from a qualified gunsmith if you are unsure about the procedure. Attempting to remove these more complex systems without proper knowledge can result in damage to your firearm.
Post-Removal and Reassembly
After removing the handguard, inspect both the handguard and the barrel nut for any damage or debris. Clean both thoroughly before installing a new handguard. Remember to reverse the steps for reassembly, ensuring that all parts are correctly aligned and secured.
Seeking Professional Help
If you encounter any difficulty or are uncomfortable performing this procedure yourself, it's always best to seek the assistance of a qualified gunsmith. Improper disassembly can damage your firearm and potentially lead to injury.
This comprehensive guide provides detailed instructions for removing the handguard on your M&P15. However, always consult your firearm's owner's manual for specific instructions and safety precautions. Remember, firearm safety is paramount. If you're unsure about any step, it's best to seek professional assistance.
