Remington mag tube extension - Carlson's Choke Tubes Remington 870/1100/11-87 Magazine Extension 7 Shot

I did my research for a mag extension and ordered the Carlson that came with a longer spring and the orange hard plastic/rubber follower. I ended up using my original metal follower but had to modify the lip of metal on the inside at the end of the threads so the follower would run smooth. Just made a slight taper. A worm drive hobby tool and 10 minutes was all it took. The quality is great and matched the bluing on my gun perfectly. I would absolutely buy again. Slight mods are expected when you modify firearms.
