How to Change a Remington Model 870 Barrel

The Remington Model 870 pump-action shotgun is one of Remington's most popular firearms, and sees use in every sector, from recreational hunting to home defense. The shotgun is also used by several law enforcement agencies, and even by a few branches of the military. Occasionally, you might find yourself needing to replace the barrel on the Model 870. Remington has made it quite simple to break down and remove the barrel, and to slide a new barrel back in.

Instructions

1. Rack the pump arm back several times to eject any shells that might be in the shotgun, then set the safety button to "on." Unloading and safeing a weapon should always be your first step whenever you are working on any kind of firearm.

2. Pull the pump arm all the way back then slide it forward about halfway down the slide.

3. Unscrew the magazine cap. The magazine cap is located at the very end of the slide, just underneath the barrel.

4. Grip the barrel just in front of the magazine tube and pull it straight out, twisting it back and forth until it has come completely free of the receiver.

5. Insert the new barrel into the receiver and push it back as far as it will go.

6. Screw the magazine cap back on, then rack the pump arm back and forth once to finish the installation.
