Night Vision Luna Elir Surefire adapter compatability

[Vicarious]

I recently decided to get an adapter for Luna to use surefire stuff, I was wondering if any new UE tail cap will fit, or if I need one of the older ones with a different thread pitch.

I got the adapter from B&H, and it seems like they have been around since before SF switched their threads so I want to make sure.

I have seen some guys post that they have done this, but I haven't had much luck finding any info about threads.

There has been a few adapters that didn't mate up well and Vlad said they were seeking a new source for the adapters.
