I’m looking for the magazine tube for a paratrooper.

I have a .22 version & two .177 versions but I don’t have the mag tubes for the .177’s

Does anyone know where I can purchase these or possibly have them made?

If you have the right tools then I’m sure these can be easily made.

I think they’re basically just like a bolt action type mechanism with a very long spring

Has anyone ever tried to make them?
