I remember someone making their own out of a Provari endcap once. Can't recall who or where the thread is, it's probably buried somewhere in the modding forum. Just another option if your search goes poorly and you choose the DIY route
I picked up one of the Odysseus 510 base connectors from COV, would that not be the same threading for the bottom of the UFS. I've been wanting to grab a UFS ever since I let my last one go, plus no matter how much I read or watch about the Oddy I can't figure out if it does what I want it to or not and if I need to expand it or not (basically what a UFS does, hold a 510 atty).
I got one from needleworks, works great.....
