Extended Mag on Remington 870: Need Help

    I bought an extended mag for my Remington 870 SuperMag (handles the 3.5" shells too). Problem is: with the extended mag, the orange follower gets stuck on two small indentations at the very end of the original mag; therefore I cannot actually get any extra shells into the magazine.

    What's the solution...should I grind out the small indentations to allow the follower to pass that point? Is there any downside to doing this?

    Or, is there some special follower I need to get to make the extended mag work?

    If anyone has dealt with this, let me know your thoughts! thanks.

    I'm pretty sure most people just drill these out when they add the mag extension.

    Thanks a lot. Any other feedback on this...would love to be 110% before I bust out the Dremel...measure twice, cut once!

    thanks!

    Some where I read you can press a large socket into the tube to remove the dimples and allow the follower to pass by... I was lucky as my 870 didn't have these dimples.

    Well, I tried the socket method. Didn't work, maybe I didn't have right socket size, but 11/16 was too big and 5/8 was a tad small, as it turned out. I ended up using the Dremel to grind down the indents. Everything seems to work well. Only downside I can see is the shiny spots of metal will be prime targets for the Rustmonster...but I'll keep it clean and dry so that won't be a problem

    Thanks guys for responding.:thumbup:

    You might try touching those up with a cold blue pen or bottle of cold blue. They also make a darker black color if that matches your gun better.
