Does the solid tube for justgg have a hole for the button? I have one of the old ggts and would like to replace the tube since it is the old alloy and it's hard to keep clean.
Yes, there is a hole for the button and the button of GGTS and JustGG is the same.
BTW: what is your brass tubes SN and are you willing to sell it, when you don't want to use it?
