Yes they can be made available if the demand exists, in limited quantities. I did not want to make 4 devices that were proprietary hence why the 7mm = 510 native connection. That being said, the IO6 came on the scene and I mfr a sample of IO6 drip tips than can be used (maintaining eGo ergonomics) on the 7mm. I have been informed that (we discussed) the bullet style drip tip will only be available as an option for folks acquiring a 7mm. The folks purchasing a 7mm will see their needs met. If the demand is strong enough, by all means more bullet shaped drip tips will be mfr and made available for the general public
I might add to demand.
