Maybe I should have researched more..

So, apparently the new Rem 870 magazine tube has these nifty little nubs on the inside to keep the spring and assembly in, however this prevents the addition of an extended magazine tube since the follower can't move past them without being turned a certain way.

I'm assuming the only way to fix this is to grind those little nubs down and add the extension, I just wanted to check and see if anyone might have any other ideas before I figured out a way to get it done.

Yup take a dremal and grind em down smooth

I took a socket with a od the same size as id of tube just beat it in with a hammer should get rid of them, that's what I did

Grind them off with a dremal. Just like Draggingknee suggested. Works everytime.

I used a dremel for the heavy work, with a rounded file to finish and smooth it out on mine.

I took this approach.

Tap the socket in a little, then tap the side of the tube a la hammer and dolly to loosen it up. Repeat.

Yep, that's how it was done the last time I was present.

Be sure to get the burrs out of there, less you suffer the same problem down the road at an inopportune moment. One rough spot can turn into an instant snag, over time.

you're gonna want to replace that junk follower that Remington uses now also....try the S&J Hardware "no jam" follower....works great in my 870 with extended tube. its around
12 dollars and they had it shipped to me in about 4 days.

I bought my 870 with the factory extension, problem solved!

 

[Ben Segrest]

Did you get this done yet? If not, I'd be happy to help you out now that finals are over.

Actually just did it. The socket thing didn't work out, they pushed past the nubs when banged in, so it gave me an excuse to buy a dremel. The factory follower worked fine, just had to smooth out the end of the magazine tube with the dremel.
