Remington 870 Magazine Dimple Removal [Poll Included]
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!

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

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.Just take a piece of steel barstock, and put a taper on the end.

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.
