Replacing or removing the gas block on your M&P15 can seem daunting, but with the right tools and approach, it's a manageable task. This guide provides a step-by-step walkthrough, focusing on safety and precision to ensure a smooth process. Whether you're upgrading your gas block for improved performance or tackling a repair, this detailed guide will equip you with the knowledge you need.
Tools You'll Need
Before you begin, gather the necessary tools. Having everything ready prevents interruptions and ensures a more efficient process. You'll need:
- A quality armorer's wrench: This specialized wrench is crucial for securely gripping and turning the gas block without damaging it. Improper tools can lead to stripped screws or a damaged gas block.
- Punch (brass is recommended): A brass punch minimizes the risk of scratching or marring your firearm's finish. You'll use this to gently tap out the gas block pin.
- Hammer (soft-faced is preferred): A soft-faced hammer helps prevent damage to the parts.
- Properly sized Allen wrenches: These are needed to remove any screws securing the gas block. Different manufacturers might use slightly different sizes, so check your specific gas block's instructions.
- Cleaning supplies: Keep your workspace clean to avoid losing small parts.
- Safety glasses: Always protect your eyes when working with tools.
- Gloves (optional): Gloves can help maintain a clean working environment and protect your hands.
Step-by-Step Gas Block Removal
Disclaimer: Always ensure your firearm is unloaded and clear before starting any disassembly. If you are unfamiliar with firearm disassembly or maintenance, seek assistance from a qualified gunsmith. This guide is for informational purposes only and does not replace professional training.
-
Prepare your firearm: Ensure the weapon is unloaded and clear of any ammunition. Double-check!
-
Remove the handguard: Depending on your M&P15 model, this might involve unscrewing the handguard cap or removing a few screws. Consult your firearm's manual for specific instructions.
-
Locate the gas block pins: Carefully inspect the gas block to identify the pins holding it in place. They’re typically located on either side of the gas block.
-
Remove the gas block pins: Using the brass punch and soft-faced hammer, carefully tap out the gas block pins. Gentle, controlled taps are key to avoid damage. Work on one pin at a time.
-
Remove the gas block: Once the pins are removed, the gas block should be loose. Gently wiggle and pull the gas block off the barrel. Some resistance is normal, but excessive force suggests a problem. Re-check your work to make sure no screws are preventing removal.
-
Clean the area: Once the gas block is removed, clean the gas block and the barrel area to remove any debris or buildup.
Potential Issues and Troubleshooting
- Stuck gas block: If the gas block is stuck, applying a penetrating oil and letting it sit for a few minutes might help. Avoid using excessive force.
- Stripped screws: If you strip a screw, you may need a screw extractor or a professional gunsmith's assistance.
- Damaged parts: If you damage any parts during removal, seek professional assistance to avoid further complications.
Conclusion
Removing an M&P15 gas block is a relatively straightforward process when done carefully and methodically. By following these steps and using the right tools, you can safely remove your gas block for maintenance, repair, or upgrades. Remember to always prioritize safety and consult a professional if you encounter any difficulties. Your firearm's safety and proper function should always be your top priority.
