Break action rocket launcher that shoots rockets propelled by co2 cartridges. Rockets are held in reusable shells and upon firing, they deploy stabilization fins thanks to rubber bands. The rockets use 12g co2 cartridges which are often used for airsoft. That makes them quite affordable and available in any airsoft store. Launcher features picatinny rails on top and bottom of the barrel, making it possible to mount accessories like scope or laser.

This is not needed but can be used to smoothen the inside of the barrel. Simply glue sandpaper to it and insert 8mm tube into the center. Mount it onto a drill and use it to smoothen the barrel. UPDATE: Added shorter 167mm barrel so it can be printed on prusa mini or A1 mini.
