I have brand new never used tubes for launching two inch shells. These are the kind you buy at Uncle Sams or where ever. Usually when you buy a morter you get one tube and six shells for reloading. I have 12 more for free. This way you can launch a whole bunch at the same time. These are the cardboard tubes that come with the package. I won't be needing them this year. If no one wants them I will toss them out.
