I have a VAMO (and an SVD soon) and a Protank2. The wobble bugs me and of course the reports of stripped threads. But I don't see how the 510 to 510 adapter will help with wobble since it will extend the length between unit and tank. Same for 510 to eGo. Seems it would be more stable if I use the eGo beauty ring that came with the PT on the 510 to eGo adapter it would become much more solid. Will it fit? Am I missing something? Would using the ring make it too far for contact?
