The Remington model 870 pump action shotgun is a perfect all around shotgun whether for hunting or home defense. It is a reliable, easy to use and affordable shotgun. For many people this is their first shotgun. For those of you who are new to using this shotgun and don't know how to properly maintain it or need a quick reminder on how to assemble/disassemble and don't have time to look up in the manual then this set of instructions is for you.
Time Required: 20-40 Minutes depending on how dirty your weapon is possibly longer
What you will need (See Image 1):
- A flat clean surface to work on
- Your Remington 870
- Clean Rags (Or old T-shirts)
- Bore Snake (12 gage or different for your model)
- CLP (Cleaner, Lubricant, Protectant - Use sparingly, a little bit goes a long way)
Step 1: ENSURE THE WEAPON IS UNLOADED
Always ensure your weapon is unloaded prior to attempting to disassemble your weapon!
With the bolt moved to the rear you can look inside the chamber to ensure that the chamber is clear
Step 2: Unscrew the Magazine Cap
Unscrew this by hand, if you can not do it by hand for some reason place your rag over the cap and gently use a pair of pliers to loosen it. After doing so you will be left with what is shown in image 2
Step 3: Remove the Barrel
After you have unscrewed the magazine cap move the pump-action about halfway back and the barrel will slide right off. After doing this you will be left with what is shown in image 3
Step 4: Remove the Forend, Bolt and Bolt Carrier
Flip the shotgun upside down and use your fingers to push on the spring loaded metal strips located inside the shotgun to flatten them out. This will release the forend, bolt and bolt carrier and you can pull it out just as the barrel was pulled out. You will likely need to press on the strips while pulling the forend. This step is tricky to describe however is easy to complete.
When you have completed this step you will be left with what is shown in image 4
