Step 2: Disassembling Your Benelli M4

Starting with the disassembly of your Benelli M4, it’s necessary to break it down into its main components. This process isn’t as daunting as it might seem. If followed carefully, ensuring each piece gets the attention it deserves, you’ll not only elongate the lifespan of your firearm but also improve its performance and precision.

First off, you’ll need to remove the magazine cap. This is done by rotating it counter-clockwise until it comes free from the rest of the device. It’s of utmost importance to keep track of each part removed, organizing them in a manner that allows for easy reassembly.

Next, comes the removal of the barrel. With the magazine cap off, I find that the barrel and forend come off quite freely. Again, store these pieces where they will be out of the way but also where they’re certain not to get lost.

Following the barrel and forend, comes the breech bolt and breech bolt slide. Here’s a quick overview of how to handle this:

  • While maintaining a firm hold on the cocking handle, slide the breech bolt to the rear and unscrew the cocking handle by turning it clockwise.
  • After removing the cocking handle, compress the breech bolt and breech bolt slide inward and remove them together.

zThis disassembly process ensures we have individual parts segregated and ready for the cleaning that follows.

As we move forward in this detailed guide, the next section will take you through the necessary products and tools for efficiently cleaning your Benelli M4. Remember, every step taken is an investment in the firearm’s reliability and lifespan. Let’s ensure we’ve got the right tools on hand when we delve into the cleaning process.

Step 3: Cleaning the Barrel and Chamber

Once you’ve disassembled the Benelli M4, you’re all set to start cleaning the individual parts. The barrel and chamber usually require detailed cleaning due to the build-up of residues from fired rounds. You’ll need the right cleaning tools and products for this job; let’s look at those first.

Gun cleaner or solvent plays a significant role in any gun cleaning job. There’s a variety available in the market, but make sure the one you choose is suitable for a Benelli M4. A high-quality gun cleaner can penetrate the setbacks and residues effectively and loosen them for removal.

Another essential tool is a cleaning rod with a bore brush. A set of differently sized bore brushes could come in handy for cleaning varying diameters within the gun. The rod moves the bore brush back and forth inside the barrel and chamber, effectively scrubbing off any residues.

A supply of cleaning patches is also necessary. After using the bore brush, push a cleaning patch soaked in the gun cleaner through the barrel and chamber, and follow with dry patches until they come out clean.

With the right tools and cleaner in hand, we’re ready to clean the barrel and chamber. Firstly, thoroughly spray the inside of the barrel and chamber with the gun cleaner. Let it sit for a while to allow the cleaning solution to dissolve greasy residues.

Next, use the cleaning rod and bore brush to scrub these regions. Make multiple back-and-forth passes until you’re confident all residues are loosened.

After scrubbing, soak a cleaning patch in your gun cleaner and push it through the barrel, followed by dry patches. This process will ‘swab out’ the loosened filth, and the dry patches absorb any remaining cleaner.

Repeat this scrubbing and swabbing process a few times until a pushed-through dry patch comes out clean. Once that happens, you’ll know the barrel and chamber are spotless.

The process of cleaning the barrel and chamber can be tedious and time-consuming, but it’s all worth it: a clean gun is a reliable, safe, and more accurate gun. Let’s move on to cleaning the other parts of your Benelli M4. After all, we’re not done yet. The next part we’ll tackle is the breech bolt.

Step 4: Cleaning the Action and Bolt Carrier Group

Now that we’ve finished cleaning the barrel and chamber, the next key component we’ll tackle is the action and bolt carrier group. This is a crucial area of the shotgun that ensures smooth and functional operation of your Benelli M4.

Firstly, start by disassembling the action and bolt carrier group. It’s simple – just follow your Benelli M4’s user manual. If you find it complex, there are numerous videos online that guide you through the process. Once you have disassembled the parts, get ready to rid them of all dirt, carbon deposits, and any potential rust.

To clean these components effectively, I recommend using a high-quality gun cleaner or solvent. Apply a small amount of solvent on a clean, soft patch or cloth, and gently wipe each component. It’s vital to reach all the corners and crevices where grime and debris tend to accumulate. Brushing the bolt carrier group lightly with a quality gun brush will loosen stubborn contaminants.

Moving forward, let’s talk about the gun oil. This isn’t just a typical lubricant. The best gun oils will provide rust prevention and superior lubrication ensuring peak performance of your firearm. Apply it sparingly at the bolt carrier group and action. It’s enough to keep your firearm lubricated without attracting dirt and dust, significantly reducing the wear and tear.

One last important note – when reassembling your action and bolt carrier group, ensure all parts align properly. A misaligned assembly won’t just affect your firearm’s functionality but could lead to long-term damage.

We’ve only got a few more crucial components to clean, starting with the shotgun’s gas system. Stay tuned as I’ll gradually guide you through each step, ensuring you maintain the optimal performance and longevity of your Benelli M4.

Step 5: Cleaning the Stock and Magazine Tube

Just as it’s paramount to maintain the action and bolt carrier group in tiptop shape, attention must also be paid to the stock and magazine tube of your Benelli M4. Over time, grime and residue can accumulate in these parts, impacting the smooth action of your shotgun.

To clean the stock, it’s always good to use a cloth soaked in a decent gun cleaner. Brush off large, noticeable debris with your hand or a dry cloth before starting. Resident dust particles can often be shaken loose but stubborn areas may require a light scrub. Avoid harsh chemicals or abrasive materials that could potentially harm the stock’s finish.

The magazine tube, on the other hand, necessitates its own special cleaning regimen. It’s not as straightforward as wiping down the stock. Before you start, ensure that the magazine tube is unloaded. Safety should never be compromised during the cleaning process.

To clean the magazine tube:

  1. Use a shotgun-cleaning rod with a brush attachment and a high-quality gun cleaner. The brush should match the tube’s diameter or be slightly larger to ensure all residue is removed.
  2. Carefully insert the brush into the tube and scrub in a back-and-forth motion, twisting the rod occasionally to get at gritty particles clinging to the sides.
  3. Following this, it’s a good idea to wipe the inside with a dry cloth to remove any remaining dust, debris or solvent.

After cleaning, apply a thin layer of gun oil on the outside of the magazine tube. This acts as a protective layer against rust and other elements. Remember, too much oil can attract dust and dirt, so usage should be sparing.

This step in the cleaning process is fundamentally important. Now that you’ve got your stock and magazine tube shining like new, it’s time to move on to the final parts. The trigger assembly and barrel await our dedicated attention. All these steps ensure that your Benelly M4 remains dependable, efficient and ready for anything.

Step 6: Lubricating Your Benelli M4

Before we move on to cleaning the trigger assembly and barrel parts, lubricating the Benelli M4 is crucial. Not only does it help reduce friction between moving parts, but lubrication also protects the firearm from corrosion, helping to prolong its life. Let’s take a look at the easy steps to effectively lubricate your Benelli M4.

Firstly, I’ll prioritize the high-friction zones. These areas include the bolt carrier, the slide rail, and the hammer track located inside the trigger assembly. Use a high-quality gun lubricant and apply a minimal amount using a small brush or a dropper. It’s best to keep it light – over-lubrication can cause blockages or attract unwanted dirt and particles, leading to poor firearm performance.

After applying a layer of the lubricant, remember to spread it evenly across these parts. You can use a soft, lint-free cloth or patches to do this. Make sure the lubricant covers the parts entirely but isn’t dripping off. You want a nice, thin film of oil – not a puddle.

While this process focuses on lubrication, it’s important to note that certain parts of your Benelli M4, like the choke threads and magazine tube from outside, require greasing instead of oiling. You should apply a small amount of gun grease to these parts, again ensuring that a thin, consistent layer is achieved.

Finally, after application, don’t rush to assemble the firearm. Instead, give it some time. Let the lubricant absorb into the metal for optimum protective benefits. Instantly putting the firearm in use might not give you the desired reduction in friction or corrosion protection.

Alright, you’re done with the lubrication part now. The next thing I’ll guide you through is cleaning the trigger assembly and barrel, so stick around.

Step 7: Reassembling Your Benelli M4

The path to successfully maintaining any firearm lies in mastering the art of reassembly. And it’s no different with the Benelli M4. We’ve lubed up and perfected our parts, now comes the meticulous task of putting it all back together.

Let’s dive right in.

Start from where we took off. Reinstall the trigger assembly first. Align the assembly keyholes with the connecting pins on the gun’s frame. Once they’re aligned, push firmly until you feel it click into place. A well lubricated gun assembly will fit back together comfortably, so don’t force it.

Next, refit the bolt carrier and slide it backward until it’s all the way in. The process is somewhat intuitive, just reverse the disassembly process. But remember, patience and precision are key components of successful firearm reassembly.

While reassembling, keep a watchful eye out. Random leftover parts are a no-go in this process. If any parts are left, you’ve missed a step, backtrack and fix it. This process needs perfect execution, the smallest miss could affect the functionality of your firearm.

To install the barrel, we’re back to the reverse of disassembly. Align it right, then twist and push it forward till it locks up with the rest of the gun assembly. Then match the handle of your bolt assembly to the hole in the bolt carrier and fix it. Make sure it’s on the right groove to avoid damage.

Lastly, lock the end cap back into position and fasten it securely. You’re nearly there, just a few more steps to go. We’ll unleash those secrets in the upcoming paragraphs.
