I was recently given a brand new Vortice RDA for free. the guy said don't use it unless i can fix the 510 pin. the 510 pin is fine it was the insulator that was creating the short. does anyone know where I can get a new 510 insulator for the vortice? its different from the regular rubber 510 insulator. This one is hard plastic. Also the pin is a hex screw instead of a flat head. its made for squanch rigs.
