A 510 carto is about 2 mm longer than a 901 atomizer. Maybe a dedicated 510 native brass connector would be needed to use with the AFS? If there is an adapter needed on the brass connector to use 510, then the 510 carto would be too long for the AFS.
Oupsssss, thats a problem. I thought that 510 cartos were the same size as the 510 atomizers
