That was along time ago.

Jesus what the hell is going on ?? all of a sudden all kinds of attys / cartos are not working .
Is this happening on other mods ? , The Buzz is a custom made threaded adapter that is high tolerance , the Infinity uses a SLB connector on it .
What type and MFG are they Vapomike ?? and are they 510 ?
IMO the 510 is the worst connector because it uses a non standard small pitch thread , they are harder to make and will cross thread easier.
So is it my infinity or atties? All the atties thread to riva fine. Well the ones that don't go on the infinity feel rough when screwing into the riva.
