I have looked into shipping drums and it is not really a feasible option for me. I will however shortly be releasing catch tabs for modification of chinese style ak drums, that will come with instructions so anyone that has acess to a welder (preferably a spot welder but any welder will do, I will also try to look into glues) can easily convert them themselves.
If someone else was willing to legally export/import them I could convert the drums but that is too much for me to take on.
