Cleaning a Barrett M82 isn’t as daunting as it might seem. It’s all about knowing the right steps and using the right tools. We’ll cover everything from disassembly to cleaning and reassembly. So, whether you’re a seasoned pro or a newbie, you’ll find this guide handy.

Remember, a clean rifle is a reliable one. So, let’s dive into the world of M82 maintenance, and keep your beast performing at its best.

Disassembling the Barrett M82

Getting right into it, the first step in cleaning your Barrett M82 is disassembly. And don’t worry – I’ve made sure that the process is beginner-friendly!

Begin by ensuring your rifle is unloaded. Point it in a safe direction, press the magazine release and remove it from the weapon. Next, pull back the charging handle to inspect the chamber and make sure it’s empty. Safety can’t be overstated in this process, and that’s why it’s paramount you confirm these two measures have been performed correctly.

Moving onto the disassembly, start by removing the monopod if yours is equipped with one. It’s a simple process: just unscrew the locking knob, pull out the monopod, and set it aside.

Next up is removing the rear pin. This is located near the back of the rifle, just above the buttstock. Press it out with your finger – the pin should slide out easily without the need for tools. Once the pin is out, the upper and lower receiver can be split apart.

Push the upper receiver forward from the lower receiver. You’ll notice this will cause the mainspring to extend out. You’ll want to remove the mainspring by pulling it straight up and out from the firearm.

Now you’ve separated the upper and lower receiver, and everything is ready to get a solid cleaning. Remember: taking care of your Barrett M82 means being thorough in your cleaning routine.

Quick recap of the disassembly process:

  • Confirm the rifle is unloaded
  • Remove the monopod
  • Take out the rear pin
  • Separate the upper and lower receiver
  • Extract the mainspring

We’ve covered the disassembly, let’s now steer our focus to the actual cleaning in the next section.

Cleaning the Barrel

Having separated the upper and lower receiver, let’s now move on to Cleaning the Barrel. It’s a crucial component of your Barrett M82 that must be maintained to ensure optimum performance.

The first step involves inspecting its overall condition. Use a bore light or flashlight to assess the inside of the barrel for any visible debris or damage. Any objects or imperfections can severely affect the accuracy of your shots.

Next up, it’s time to get scrapping. Handy tools like a bore brush and cleaning rod are essential for this task. Set your cleaning rod with the appropriate sized bore brush. Once done, apply some gun-specific cleaning solvent onto the brush. A pro tip here: Don’t drench it. Excessive solvent could potentially harm the inner-part of your barrel.

run the brush through the barrel, starting from the back and outward through the muzzle. Don’t reverse the brush in mid-pass. It’s recommended to go through these steps several times, ensuring that the barrel gets thoroughly scrubbed.

Removing the loosened debris and gunk is the next task at hand. Use a jag or loop on your cleaning rod, and attach a patch. Once again, apply some cleaning solvent, but be mindful not to soak the patch. Running the patch through the barrel will take care of the unwanted elements therein.

Last but not least, lubricate the barrel. Take a clean patch, mildly apply some gun-specific lubricant, and run it through the barrel.

Remember, maintaining your gun is not a race. It’s a responsibility. Take your time, be patient, and focus on the job at hand. Let’s move on to the next step in our cleaning process: lubricating other parts of the Barrett M82.

Cleaning the Bolt Carrier Group

Subsequent to cleaning the barrel, we’ll extend our attention towards the bolt carrier group. This group is considered the ‘heart’ of the Barrett M82 rifle. Dirt or corrosion in this area can significantly compromise the rifle’s performance. Cleaning it involves meticulous steps to ensure no debris gets left behind and the rifle functions optimally.

First off, disassemble the bolt carrier group. Start with the bolt carrier by pushing the bolt to its rear position. Now, you may remove the cotter pin, freeing the firing pin. The bolt cam pin can then be turned and removed, allowing you to take out the bolt itself. Take care during this process – misplacing these small pieces may impede reassembly. I recommend working on a tray, where all components can be safely kept until required again.

After disassembling, soak all the components in a cleaning solvent. Not only does this loosen tight dirt and traces of powder residue, but it also makes scrubbing easier and more effective.

Once soaked, it’s time to scrub them using your cleaning brush. Be patient and make sure you get into all corners, crevices, and holes. Pay particular attention to the bolt – it’s crucial that this part remains spotless and well maintained.

After scrubbing, rinse the parts with clear water if your solvent requires it, or simply wipe them dry if not. Double-check to ensure all the parts are as they should be – free of dirt and debris.

Lastly, apply a thin layer of gun lubricant to these parts. It’s not necessary to assume that more lubricant equals better performance. Excessive amounts can attract more dust particles than necessary, leading to more cleaning and maintenance. The final touch, reassembly, goes smoother with a well-cleaned and adequately lubricated bolt carrier group.

This part of the cleaning process can, indeed, be quite intensive. Unavoidably so, if you’re looking for prime performance from your Barrett M82. The reward is assurance – knowing that your gear is clean, efficient, and reliable. Make this a habitual process, and you’ll find that responsibility comes hand-in-hand with gun ownership.

Lubrication and Reassembly

After we’ve soaked, scrubbed, and dried each component, the next crucial steps are lubrication and reassembly. These are essential for ensuring the smooth function and longevity of any Barrett M82. A common mistake I see among novices is using too much lubricant, which can collect dust and debris, potentially causing malfunctions.

The Golden Rule: Use Gun Lubricant Sparingly.

When it comes to applying gun lubricant, sparingly is the buzzword. Small drips and drops are more effective than excessive amounts. We should focus specifically on the bolt’s high-wear areas. It’s best to apply lubricant using a clean, lint-free cloth or a fine brush to ensure accuracy, and we must avoid making a mess.

Moving on to reassembly. Now, I always tell my readers: the reassembly process is simply the disassembly process in reverse. Therefore, if we’ve kept all the components organized, this part should be a breeze. We start with the bolt and extractor, followed by the other parts.

Here’s a quick and simple guide:

  • Install the extractor onto the bolt
  • Attach the bolt to the bolt carrier
  • Reinstall the firing pin
  • Reassemble the rest of the bolt carrier group

Pro Tip: Test the Bolt Carrier Group After Reassembly.

Testing the bolt carrier group after reassembly is an essential step that a lot of people overlook. Here, we are checking if all the parts are functioning correctly. Simply cycle the bolt carrier group manually a few times. If everything’s smooth with no blockages or hesitations, we’re good to go.

Remember, cleaning a Barrett M82 isn’t about speed – it’s about accuracy and careful attention to detail. Taking the extra time to lubricate properly and reassemble attentively will yield significantly better results, both on the range and in the field.
