What about this one that Cromwell posted, at VaporBeast:
Accessories | 18650 Fin Base | VaporBeast
It looks like it's 22mm, under that Freakshow.
What I need to know is, if you don't actually want more airflow, can you fix it so it doesn't give more air? I just need a way to connect my Achilles once I get the threads fixed, that won't screw up the threads again.
Apparently the raggedy threads in my new iPV Mini have ruined the threads on my favorite Achilles
Nice folks in the Achilles thread gave me a link to this ->
7mm x .5 Metric Right hand Die M7 x 0.5mm Pitch -- to fix them, and once they're fixed, I don't want the iPV Mini to ruin them again, so I guess i need to get one of these adapters to permanently affix to the iPV Mini.
