Permanent mag tube plug

[JDForBrkFst]

I was wondering what options people have come up with for permanent plugs in their autoloader shotguns? I saw one Cbabes did, any other methods?

To prevent the inevitable why, with a mag extension on a semi it can't hold more than 5 of the biggest shell that the scattergun is marked for.

I found a broom stick that had a handle just a bit smaller than the inside of the extension, cut a chunk off, and tested and trimmed to the right length.

I intended to secure it with a rivet through the end of the extension, but couldn't find one long enough in my tool box. So I epoxied it in. Way more permanent than the rivet.

I epoxied a spare follower at the end of the tube. Works like a charm.

Fabarm shotguns have some kind of white plastic piece that is wedged in there and looks like it's glued in then they cut the spring as well.
