Removing Dimples in Magazine Tube of Remington 870
If you own a Remington 870 pump action shotgun then you will probably want to install a magazine extension at some point in order to hold more ammunition. The only problem is you have to remove the dimples that are in the magazine tube first before you can install the extension. Many shotgun owners are afraid of this process because they risk breaking their weapons when trying to remove these dimples. That is why if you are a total newbie to modifying shotguns yourself then you should have a professional do it for you. Otherwise, take it one step at a time.
First, you want to make sure you have a magazine extension that is made exclusively for the Remington 870. There are extensions available that hold 1 to 4 and even more rounds of extra ammunition. When you are finally ready to install the extension, you have to go ahead and remove the dimples. There are two common methods for doing this. You can either drill out the dimples and leave small holes in their place or insert a socket into the magazine tube and then hammer it in order to press out the dimples.
Both methods are good but I recommend using the drill method because sockets can get stuck in the magazine tube to the point where it is impossible to get them back out. Some people even end up purchasing new shotguns because they failed to get the socket out of the magazine tube. So your best bet is to drill the dimples using a Dremel tool or drill. This will allow you to make the holes faster while ensuring the safety of your gun. Since there are two dimples found on a Remington 870 magazine tube, this means you will be making two holes. Now you will be able to install the magazine extension with no problems.
Dremel/drill tools are fairly inexpensive and you can pick them up for about $40 to $80 at your local hardware or home improvement store. You don’t have to be a handyman in order to learn how to operate this device. All you have to do is hold the tool in your hand and gently apply the end to the dimple in the tube. If you still have questions or doubts then you can watch YouTube video demonstrating this process for you:
Then just apply what they do to your own magazine tube and it should work out fine.
