I'm having a problem getting my TOBH v2 to sit flushed on my king mod. When I screw it down finger tight it sits very crooked on my mod. I took the bottom pin out of the top piece of the mod and still got the same issues. Put the atty on the same king mod at my vape shop and still the same problem. It sits flushed on my nemesis no problem. I've seen the pics of the atty sitting flushed on king mods. Any advice?
