5card. The 510 extender can be used in place of the eGo adapter for attachments that do not need the large threads. For example, with the 510 extender, you can screw on a EDCMC and it keep it close to the PV. The outer threads are not needed with these carto's. You just need to allow for enough 510 thread length so that the outer shell doesn't bottom out against the PV before the 510 can make contact.
LD. I could not find any in brass, and yes the eGo adapter has the outer threads Though hanging out in here while we were impatiently waiting for our IPro's had me buying new stuff for days. Haven't used my EDCMC's since those dang Fluzos and Visions came in.
Ya, I know. I used an adapter to run the tank on this Ikon that has outer threads on it.
