The Benelli M4 shotgun is a powerful and reliable firearm that is popular among shooting enthusiasts and military personnel around the world. This semi-automatic shotgun is known for its durability, ruggedness, and ease of use. Regular disassembly and cleaning are essential to ensure the optimal performance and longevity of your Benelli M4 shotgun.

Safety Precautions

Before you begin disassembling your Benelli M4 shotgun, it is crucial to prioritize safety. Always wear proper safety gear, including eye protection and gloves, to protect yourself from any potential accidents. Additionally, make sure the shotgun is unloaded and the chamber is clear before starting the disassembly process. Handle all ammunition and parts with care to prevent any mishaps.


To disassemble your Benelli M4 shotgun, follow these step-by-step instructions:

Removing the magazine tube cap

Start by unscrewing the magazine tube cap located at the end of the shotgun’s magazine tube. This allows you to access the internal components of the shotgun.

Taking off the barrel

With the magazine tube cap removed, you can now detach the barrel from the receiver. Carefully slide the barrel forward until it is completely separated from the shotgun. Set aside the barrel for cleaning.

Separating the bolt assembly

Next, you need to separate the bolt assembly from the receiver. Push the bolt handle forward, then rotate and lift it to unlock the bolt. Once the bolt is unlocked, pull it straight back to remove it from the receiver.

Removing the trigger assembly

To remove the trigger assembly, simply push out the trigger pins located on either side of the shotgun’s receiver. Once the pins are removed, the trigger assembly can be lifted out of the receiver.

Cleaning Materials

To effectively clean your Benelli M4 shotgun, gather the following cleaning materials:

Choosing the right cleaning solvents

Select the appropriate cleaning solvents for your shotgun. Consult the manufacturer’s recommendations or seek advice from a knowledgeable gunsmith. Avoid using harsh chemicals or solvents that may damage the firearm.

Cleaning brushes and rods

Use cleaning brushes and rods specifically designed for shotgun cleaning. Different calibers and gauges may require different size brushes and rods. Ensure you have the correct tools for your Benelli M4.

Lint-free cloths

Lint-free cloths are essential for wiping down and drying the components of your shotgun. Avoid using regular towels or cloths that may leave behind lint or fibers.

Cleaning Procedure

Follow these steps to clean your Benelli M4 shotgun:

Cleaning the barrel and bore

Attach a cleaning brush to the end of your cleaning rod and apply a suitable solvent to the brush. Insert the rod into the barrel and push the brush back and forth to remove any residue or fouling. Repeat this process several times until the barrel is thoroughly cleaned. Use a lint-free cloth to wipe away any excess solvent.

Removing carbon buildup

Carbon buildup can accumulate on the bolt assembly and slide. Use a cleaning brush and solvent to scrub away any carbon residue. Pay special attention to areas where carbon tends to accumulate, such as the bolt face and firing pin.

Cleaning the trigger assembly

Clean the trigger assembly using a cleaning brush and solvent. Carefully remove any dirt, debris, or residue that may have accumulated. Once the assembly is clean, wipe it dry with a lint-free cloth.

Inspecting and Lubricating

After cleaning your Benelli M4 shotgun, take the time to inspect the components for any damage or wear. Pay close attention to areas that experience high levels of stress or friction, such as the bolt assembly and trigger assembly. If any parts show signs of damage or wear, they should be replaced by a qualified gunsmith.

Apply a high-quality gun lubricant to the necessary moving parts of the shotgun. Pay particular attention to areas with metal-to-metal contact. Proper lubrication reduces friction and helps to ensure smooth operation.

Slide the bolt assembly back into the receiver, aligning it with the rails. Push the bolt handle forward, rotating it to lock the bolt into place.

Reassembling the magazine tube cap

Screw the magazine tube cap back onto the shotgun’s magazine tube, ensuring it is tight but not over-tightened.

Before moving on, perform a visual check to ensure all components are properly aligned and secured.

Function Test
