The shotgun pictured is a Remington 870 XCS marine Magnum, but the measures will it is in the exact same for any type of of the Remington 870 family. The steps for other shotguns are comparable as well. Prior to beginning, ensure that the gun is unloaded, and also that the hammer is no cocked.

Step 1: Assemble her cleaning supplies

Get her cleaning supplies together. Every person involves prefer certain products; my favorites are shown. From left to ideal are a boring snake, a clean rag, a clean patch, and gun solvent/protectant. The bore snake will certainly be used to clean the barrel, the clean rag and also cleaning patch will be provided to wipe under the interior and also exterior surface of the gun, and the solvent/protectant will be provided to clean the barrel, interior and exterior surfaces, and the cause group. Because that a solvent/protectant, I use Break cost-free CLP, and also highly recommend it.

Step 2:Unscrew the newspaper cap

You should be able to unscrew this through hand, yet if that is stuck then wrap it through a cloth (to protect against scratches) and then use pliers to gently unscrew it. Use caution, as the magazine cap is spring loaded and also will pop off if friend don’t hang on to it together you unscrew it.

Step 3: Remove the barrelonce the magazine lid is off, the barrel will certainly slide appropriate off the gun.

Step 4: Remove the forend and also bolt carrier assembly

Flip the shotgun upside down and also use her fingers to push out the feather loaded metal strips. By “push out” I mean to press from the inside of the opening, attempting to flatten the end the metal strips. This will certainly release the forend, and also you can pull that out simply as the barrel was pulled out. Girlfriend will most likely need to press in the strips when pulling the forend, and also then repeat the procedure a pair times. This step is the hardest come describe but is straightforward to actually do.

Step 5: Remove the cause groupThere space two pins that hold the trigger group in. To eliminate the create group, use a wood dowel stick or tap about the dimension of the pin to tap out the pins. On my Remington 870, the larger of the pins comes out easily, when the smaller of the pins requires gentle tapping with a hammer. Keep in mind that girlfriend will want to usage a wooden dowel rod or other tool the won’t scrape the gun. I’ve used screws, nails, and also screwdrivers come tap the end my pins, which is why there space superficial scratches. Once you eliminate the pins, the trigger group can be slide out native the bottom.


Step 1: Clean the barrel

Spray few of the solvent/protectant right into the barrel, then thread the boring snake into the barrel indigenous the breach end. Pull the boring snake with the barrel a few times, till the inside of the barrel watch clean and also shiny. Don’t forget come clean the exterior that the barrel too.

Step 2: Clean the interior and also exterior surfaces of the shotgun

Spray a few of the solvent/protectant onto the cleaning cloth and/or patches. Use them come wipe down the interior and also exterior surfaces of the gun. A small of the solvent/protectant go a long means – score is to clean the gun, not to progressive the stock price that the solvent/protectant manufacturer. I have used the same can of Breakfree CLP for over 30 cleanings of mine Remington 870 XCS naval Magnum.

Step 3: Clean the create Group

Ensure the the safety and security is on, due to the fact that pulling the create now could reason the hammer come strike your finger, causing a great deal of pain and also injury. Friend could additionally damage the cause group. In fact, the hammer must not also be cocked (as pointed out above) yet keep the security on for good measure.Remington claims that the cause group must be cleaned using RemOil, your particular. Solvent/protectant brand. I occur to have a can of it, for this reason I usage it to clean my create group. The said, ns seriously doubt the it is important to use RemOil. To clean the cause group, simply spray it through the solvent, shake it off, and let the dry. If I’m in a hurry I’ll use compressed air and dab it v a fabric to remove excess solvent/protectant.


Step 1: Reinsert the create groupSlide the trigger group ago in to place, and tap in the pins which hold it in place.

Step 2: Reinsert the forend and bolt carrierSlide the forend ago in. You may need to push upon the same steel strips the you pressed upon when you removed the forend and bolt carrier.

Step 4: Reinsert the newspaper cap and also related items

Insert the (orange) shell follower into the newspaper tube, adhered to by the spring. Then location the magazine lid over the spring and also screw it in. The is spring loaded, however reinserting that gets really easy with practice. Hand tighten the newspaper cap until you cannot revolve it any further. Using pliers is generally not recommended because using too lot torque can damages the shotgun.
