I have the fusion drip...I'm not sure if It fits the AFC; I heard that it did not and I haven't tried it...I do, however, use it as my every day tip with the standard cap I use on my unmilled Reo Mini...I absolutely love it. Although it uses an o-ring enclosure like the cyclone top caps, it's just a tiny bit looser, allowing easy access to your coil and wick with out having to peer
through the tiny 510 side of the atty which never works anyway. It's a simple way to adjust positioning, check fluid amounts, and see how the atomizer squonks and distributes liquid based on any adjustment. Highly recommended and the reason why one of my AFC caps stays at home (again I was TOLD it doesn't fit and for some silly reason I didn't try it on either of my other two reos that also sport cyclones--I'm sure this will be confirmed or denied shortly)
