Yeah I'm specifically looking for 510 sized *press/friction* fit drip tips with a narrow bore though. I have a Heron clone with a DT well that's a little too deep, and condensation forms in the gap rather quickly which causes gurgling. A press fit would solve this issue right away, but I don't want a wide bore drip tip for an RTA that I build at 1.2 ohms on heheh.
