I have wanted to be able to use my 510 drip tips with my 306s for a while now, and the universal seemed like my only option. But I wanted something metal. So what I did was take apart some of my old attys, and I found that the atty sleeves with the fat band at the bottom fit a 306 like a glove... Works great and basically free if you have old attys. I took the old atty apart by attaching it to a dead eGo, and then twisting with pliars... This is the part that you could mess up if you are using any painted, (non bare-metal) old atty as the pliars like to slip and scratch the paint badly...
The silver one on the the middle newman's box is my go to 306 atm, 1.8ohm and no bridge, ss drip tip. And a black ceramic drip tip in the black adapter close-ups.
Edit: the pink one on the right is how 306's look normally, (smartvapes was sold out of the blacks ones at the time,) and the tank on the left is just for show I guess, since I don't use cartos anymore.
