5/8 x 24 unef

As per title, looking for a decent end of barrel (not reflex over barrel) moderator.. Struggling to find many threaded in 5/8” x 24 UNEF. I’ve a nice Ase Utra CQB on my .204, and although too small and threaded in 18x1, I can’t find anything other than really expensive Wildcat options in .223...
