Hey Vaperz, i am currently searching for somewhere that i can get a top cap, and a bottom switch assembly for my copper mod as i have 2 tubes one 18650 and one 18350 but only one top cap and switch assembly. i would like to complete both so i dont have to take them apart all the time. dont really care if its SS or Brass just really looking to find another set. if anyone knows where i could find it or possibly wants to get rid of theirs let me know.
