My preferred carto for both my Ego knockoff and my Big Chuck is the EMDCC, but I don't have a good solution for fitting it to the Chuck. A 510/Ego adapter is too short (I tried shortening the EMDCC with a hacksaw, but it's clunky and I think I ruined a new carto doing it -- nasty primer-tasting vapes after I sawed it, but maybe it was just bad already), while the longer extension I've found is too long -- there's about a 3/8-inch gap between the bottom of the carto and the top of the Chuck.
Is there a "Goldilocks" solution out there? Something that's longer than the Ego adapter but shorter than the 1-inch extension? Ideally I'd like the Chuck/carto gap to be like a millimeter or two, small enough that it's not noticeable unless you look closely. Looks like something with a tube length (not counting threads) of 5/8" should be about right. Does such a thing exist?
