I am getting ready to add a Nordic Components +2 magazine extension to my Remington 870 but I need to remove the dimples in the magazine tube first.

I have read numerous suggestions on the best method to use... drilling them out, using a dremel to file them, tapping a socket down the tube to push them out, etc... and I am having trouble deciding which to go with. From things I have read, there are some inherent risks involved with each one of these methods.

I do see tons of pictures of peoples' 870's that have magazine extensions, so I thought I would create a poll to see what the most popular dimple removal method is.

Your votes, recommendations and experiences are appreciated!

DONT do the pound on a socket method. Just grind them out with the dremel. Trust me, the pound method DOES NOT work

Yea... I read some horror stories of the tube getting so out of round or expanded that the barrel and magazine cap would not go back on.

There seem to be many people recommending it though.

I tried the pound method. I just couldn't get it to pound out smoothly. So, I drilled that sucker and sanded. 100% dy-no-mite! No problems at all.

About how big of a hole do you have in the tube now? Do you have any problems with shells or the follower hangin up?

Drilled and sanded, don't recall what size bit I used though.

Drilled and sanded. Make sure you spray some flat black paint on all the bare metal when your done (for rust reasons) I did this to my buddies 870 two years ago and it's ran flawlessly.

I used a round file, took a little while but worked great! If you have a dremel that would be even better. I put soft cloth in the magazine tube just below where I was filing to keep file dust (grinder dust) from going down the tube. Of course run a cleaning rod through with a clean cloth several times to remove any dust that does get in to the magazine tube.

Other.

I bought an older 870 that didn't have 'em.

1/4" drill bit. Rounded file. Done. Took about 15 minutes. Flawless operation with a Wilson Combat 2-shot extension.

I've been slacking on my shotgun. I still need to add the mag extension. I'll probably do drill and sand method.

I think I may wind up drilling it but I haven't decided for sure yet. It sounds like it may be easier and have the least likely chance to scratch up the insides of the tube.

The extension I ordered from MidwayUSA got here today and looks great now just gotta find the time to do the modification.

I've never done it, but I have an idea for a special tool.

Just take a piece of steel barstock, and put a taper on the end. Radius all the edges so there's little to no chance to scratch the tube. Make it so it could also be used as a mandrel to peen the dent out from the outside.

This guy's idea looks pretty good too.

Maybe a combination of the 2 with a specially modified C-clamp.

Saw that link too... Seems like it may be the safest option but will take longer without all the materials together.

Ultimately decided to drill out the dimples with a 1/4" bit, then used a dremel to shave down the burrs on the inside of the tube.

Functions flawlessly loading and feeding, and the extension looks great.
