The Benelli M4 is a popular semi-automatic shotgun known for its reliability and versatility. One of its key features is the collapsible stock, offering adjustability for different shooters and situations. However, removing the collapsible stock might be necessary for cleaning, maintenance, or modifications. This guide provides a step-by-step walkthrough on how to safely and effectively remove the Benelli M4 collapsible stock. This process applies to both the standard and tactical versions of the M4.
Understanding Your Benelli M4 Stock
Before we begin, it's crucial to understand the components of your Benelli M4's collapsible stock. The stock typically consists of the following:
- Stock Tube: The main cylindrical part that houses the buffer tube and recoil mechanism.
- Collapsible Mechanism: The internal components that allow the stock to fold and extend.
- Stock Buttpad: The rearmost part that rests against your shoulder.
- Retaining Pin(s): These secure the stock to the receiver. The exact number and location vary slightly depending on the model year and specific configuration of your M4.
Tools You'll Need
Before starting any disassembly, ensure you have the correct tools. Improper tools can damage your firearm. You will need:
- Punch: A small, sturdy punch (brass is preferred to avoid scratching) – this is crucial for removing the retaining pin.
- Appropriate Sized Allen Wrench: This depends on the specific model of your M4 – consult your owner’s manual.
- Cleaning Rod (Optional): Useful for clearing out any debris within the stock tube.
- Soft Cloth: To clean and protect your firearm during and after the process.
Step-by-Step Guide to Benelli M4 Collapsible Stock Removal
Safety First: Always treat your firearm as if it were loaded. Ensure it's unloaded and the chamber is clear before beginning any disassembly.
1. Secure the Firearm: Place your Benelli M4 on a stable, padded surface. This prevents accidental damage to the firearm or yourself.
2. Locate the Retaining Pin(s): Carefully examine the area where the stock connects to the receiver. You'll typically find a small retaining pin or pins securing the stock tube.
3. Remove the Retaining Pin(s): Use your punch to carefully tap out the retaining pin(s). Apply firm, even pressure. Avoid using excessive force, which could damage the pin or the receiver. If the pin is stubborn, a drop of penetrating oil might help.
4. Separate the Stock: Once the retaining pin(s) is removed, gently pull the collapsible stock away from the receiver. It might require a slight wiggle or twisting motion to disengage it completely.
5. Inspect and Clean: Inspect both the receiver and the stock for any debris or dirt that accumulated in the mating areas. A cleaning rod can be used to clean out the stock tube if necessary.
6. Reassembly (Reverse Process): Reassembly is the reverse process. Ensure the stock is properly aligned with the receiver before inserting the retaining pin(s). Tap the pin(s) back into place using the punch.
Troubleshooting
- Stuck Pin: If the retaining pin is stuck, apply a penetrating oil and let it sit for a few minutes. Try again using the punch. If it's still stuck, seek assistance from a qualified gunsmith.
- Damaged Pin: If the pin is bent or damaged, replace it with a new one of the correct size.
- Difficult Separation: If the stock is difficult to separate from the receiver, double-check that you've removed all retaining pins. Gently rock the stock back and forth to help it disengage.
Important Considerations
- Always refer to your owner's manual: This guide provides general instructions. The exact procedure may vary slightly depending on your specific Benelli M4 model.
- Seek professional help if needed: If you're unsure about any step, consult a qualified gunsmith. Improper disassembly can damage your firearm.
- Proper maintenance: Regular cleaning and lubrication of your Benelli M4 are essential for its proper functioning and longevity.
By following these steps, you can safely remove the collapsible stock from your Benelli M4. Remember to prioritize safety and always refer to your owner's manual for specific instructions tailored to your firearm's model.
