How to Clean a Remington 870?

The Remington 870 is a gorgeous piece of art that many shooters prefer over other models. Its popularity remains intact after all these years, and it is still relevant to this day because of its high efficiency, durability, and how comfortable it is to use it.

To keep its performance at an optimum level, you'll need to maintain it periodically. Doing the maintenance allows the rifle to continue offering high-quality performance, but it also gives you the opportunity of getting to know how it works.

Here, we'll go through the different steps you must follow to maintain your Remington 870 clean of particles, debris, and other damaging elements.

Disassembling the Remington 870

Before getting into the proper maintenance process, you must disassemble the rifle first. Having all the pieces out makes cleaning so much easier.

After unloading the rifle, it is time to get to work!

Removing the Magazine/Tube

You can find the magazine cap under the barrel. While jumping outwards, it is there where the pump handle stops.

To remove the cap, twist it towards you, or do it counter-clockwise. If it is too difficult, use any tool at your disposal to get a better grip over it. Put a towel around the cap, and use a pair of pliers as the last result if you can't twist it around.

Be careful, though. Using the pliers on the rifle could produce scratches or mar the overall finish of the rifle.

The cap is spring-loaded, meaning that as you get closer to hitting the last thread on it, it will likely try to pop out. To keep it from flying across the room, put some small pressure over it when you're unscrewing it.

After removing the magazine cap, separate the receiver from the rifle barrel, and you'll be ready to remove the barrel, as well.

Removing the Bolt Carrier

Now, you can move forward to the next step: removing the bolt carrier and the fore-end assembly device.

It may look tricky, but it is quite easy. The whole unit is put together and assembled by a couple of pins that decompress to move it up and down. Pretty similar to how an umbrella works.

Place the Remington 870 upside down, and take a closer look at the port located on the bottom, right where you load the shells. In there, you'll notice two metal strips with the spring-loaded mechanism. To take them off, press it using your fingers until they release their grip.

After doing that, the fore-end, like the barrel before, will be easier to slide out.

Removing the Trigger Group

This step is one of the easiest while disassembling the Remington 870. Before you do it, make sure the rifle safety is on. At this point, it would be embarrassing to cause an accident hurting yourself.

Now that you've taken the necessary precautions, you need to tap both of the pins located over the trigger housing.

The bigger tap doesn't require much effort to come out, but you might have some issues taking care of the smaller one.

Keep in mind that using tools like the screwdriver could break or produce scratches, ruining the finish of the rifle.

Instead, try using golf tees. It might sound weird, but many professional recommend using it because of its two ends. One end has a small point, and the other has a large base. They create a convenient flat, broad surface capable of tapping the pin and get it out.

Regardless of the tool you use, getting the whole unit is a necessary step to do the proper maintenance process.

Once it is out, clean all of the pieces from the unit before moving to the other parts.

Cleaning the Remington 870

Disassembling the rifle is the previous steps to the maintenance. Now, after getting all of the pieces out and separated, the cleaning begins. You could start cleaning the bore.


The solvent you use to clean the rifle depends entirely on your personal preference. However, there are different substances capable of leaving a perfect and shiny look on the rifle. Some of those substances are Hoppes No. 9, M-Pro7 and Rem Oil.

Bore Cleaning

Spray a small amount of your preferred solvent into the barrel, and follow up by taking the boresnake out. Run the snake from its chamber to the barrel a couple of times. Repeat this process until the barrel looks shiny and clean in the inside, without any particles or debris lying around.

Don't forget to clean the bore's outside, too. This part is in contact with the hands, which means that it gets dirty regularly. You can use the same substance you used to clean the inside of the barrel. If you can't use the boresnake, the cleaning rod works, too.

Clean Everything!

We focus on the main pieces of the Remington 870, but there are more to it, of course. Make sure to clean every side and every part of the rifle. Check the stock to inspect if it needs cleaning, and keep an eye out to spot marks and stains over the rifle.

The Remington 870 is a beautiful piece of art, and you should keep it as clean as possible.

Reassembling the Remington 870

Now that you're pleased with your maintenance results, it is time to reassemble the rifle.

Step 1: Install the Trigger Group

Make sure there isn't any cleaning lubrication excess remnant over the piece, and proceed to reinstall it in the rifle. To do it, put the trigger group back in its right place in the rifle, and use the two pins to secure it.

Step 2: The Bolt Carrier

The next step is to introduce the fore-end and the bolt carrier. Slide the fore-end inside the rifle. It might be necessary to decompress the metal strips that you pressed before to release both of these pieces.

Step 3: The Barrel

It is quite simple: insert the barrel back by sliding it into the housing. Right from where you took it.

Step 4: The Magazine Spring and Cap

Place the spring in the rifle, and follow up with the magazine cap. Then, tighten it together. It may require a certain amount of pressure to install it. Don't use the pliers for this step, or they could damage the rifle.


And there you have it! Your Remington 870 is completely clean and ready for the next task. The maintenance process could be tedious sometimes, but it is always necessary to keep our accessories and rifles working at their best capacity.
