they are 1mm thicker just to fit the upcoming AVS sweety
And all connectors are nickel-plated. Also all the buttons have a nickel-plated case and there are nickel, aluminium and brass locking nuts.
This batch will have all brass GGTBs, all nickel and all aluminium. I wanted to make more caps so all of you could have the opportunity to choose what cap and what tube you want but 500 GGTBs are already too much for me, I couldnt make more and assemble them. I know that they are very few because each seller will have only 100 units but thats all I can do for now
