Your Safety is the Highest Priority
Verify Unloaded
Before beginning any work, *absolutely* confirm the firearm is unloaded. Visually inspect the chamber, magazine tube, and any other areas where a round might be present. Open the action and physically check. Repeat this process several times throughout the disassembly and reassembly.
Eye Protection
Wear safety glasses to protect your eyes from any debris or fragments that might dislodge during the process.
Hand Protection
Gloves provide added grip and help protect your hands from any sharp edges or potential contaminants.
Workspace
Choose a well-lit workspace with a clear surface. A clean area will help prevent losing small parts.
Gathering the Essential Tools and Materials
Wrench
You’ll need a wrench, typically of the appropriate size for the stock bolt. Precise sizes can vary slightly, so ensure you have a metric set to cover all possibilities. A good adjustable wrench can also work in a pinch.
Screwdrivers
Depending on your specific Benelli M4 model, you might encounter screws securing other components. A set with both Phillips-head and flat-head drivers is always a wise choice.
Punch and Hammer
These are essential for removing pins, if your particular stock configuration utilizes them. Make sure to have a punch set that contains multiple sizes, so you can choose the punch size appropriate for the pins on your shotgun to prevent damaging parts.
Soft-Faced Hammer or Mallet
Helpful for gently persuading stubborn parts to separate without causing damage. A rubber mallet or a hammer with a rubber or plastic head is ideal.
Gun Cleaning Solvent and Oil
You’ll want these on hand for cleaning and lubricating any parts during reassembly. Consider using a quality gun-specific solvent and oil.
Bench Vise (Optional, but Recommended)
A bench vise will securely hold the Benelli M4, making the process much easier and allowing you to use both hands without worrying about the firearm moving. Soft jaws for the vise are highly recommended to prevent damage to the receiver.
Protective Cloth or Mat
Place the Benelli M4 on a protective cloth or mat to prevent scratching the finish during the disassembly.
Beginning the Stock Removal Procedure
The Unloading Confirmation (Again)
Before proceeding any further, and it cannot be overstated, double-check to ensure the Benelli M4 is unloaded. Verify the chamber is empty and the magazine tube is clear of any rounds.
Securing the Firearm
If you have a bench vise, secure the Benelli M4 in it. Use soft jaws or padding to protect the firearm’s finish. Position the shotgun so that the stock is accessible.
Locating the Stock Bolt
The primary connection point for the stock will be a large bolt, typically located at the rear of the receiver where the stock meets the receiver. This bolt is often easily visible.
Loosening and Removing the Stock Bolt
Use the wrench to carefully loosen and remove the stock bolt. Apply even pressure and avoid stripping the bolt head. If the bolt is particularly tight, a penetrating oil might be necessary. Allow it to soak for a few minutes before attempting to loosen it again. If you’re having trouble, consult a professional.
Inspecting for Additional Pins or Components
Some Benelli M4 models may have additional pins or small components that secure the stock. Carefully inspect the area where the stock attaches to the receiver. Look for any pins that need to be removed.
Removing Pins (If Applicable)
If there are pins, carefully use the punch and hammer to drive them out. Select the correct punch size to avoid damaging the receiver or pin. Remember the orientation of the pins for easy reassembly. Take pictures of the pin locations before removing them to make it easier during the reassembly.
Separating the Stock
Once the bolt and any other fasteners are removed, you should be able to separate the stock from the receiver. Gently pull or slide the stock away from the receiver. If it’s stuck, try a light tap with the soft-faced hammer or mallet. Avoid excessive force.
Taking Care After Removal: Cleaning and Inspection
Cleaning the Receiver
Clean the area where the stock attaches to the receiver. This will remove any old lubricant and debris, preparing the surface for reassembly.
Inspecting the Threads
Check the threads on the receiver and the stock bolt for any damage or wear.
Storage of the Stock
If you’re storing the collapsible stock, store it in a safe and secure location, away from children and unauthorized individuals. Consider a gun safe or a locked cabinet.
Putting Everything Back Together: Reassembly Steps
Aligning the Stock
Carefully align the stock with the receiver. Make sure all the components are properly aligned.
Inserting and Tightening the Stock Bolt
Insert the stock bolt and thread it into the receiver. Hand-tighten the bolt, and then use the wrench to tighten it firmly, but do not overtighten.
Reinstalling any other components, such as pins
If there were any pins to remove, insert them, making sure that the original orientation is followed, and secure them.
Function Check
After reassembling the stock, perform a function check to ensure everything is working properly. Operate the action and check for any unusual sounds or resistance.
Final Unloading Confirmation
As a final, essential step, *double and triple check* that the Benelli M4 is unloaded.
Addressing Potential Challenges
Stuck Bolts
If the stock bolt is stuck, try penetrating oil. Allow it to soak, then attempt to loosen the bolt again. If it still won’t budge, consult a gunsmith.
Damaged Threads
If the threads on the receiver or the bolt are damaged, the bolt may not tighten properly. Replace the bolt, or consult a gunsmith for thread repair.
Difficulty Removing or Installing Pins
If the pins are difficult to remove or install, make sure you have the correct punch size and that you’re applying force evenly. A small amount of oil may also help.
