HELP: HUXWRX FLOW 9K Ti Tri-Lug Adapters

I just ordered my HUXWRX flow 9kti for my AP5-P and am at a complete loss as to what tri-lug muzzle adapter will be compatible with it (not to mention nearly every model of tri-lug adapter is out of stock). The specifications for the suppressor simply say it is HUB compatible, but no actual thread pitch is provided. This is my first suppressor purchase and while not the quietest or lightest I chose this one for the reduced back pressure since I am a left handed shooter. I don't have much to spend on an adapter and it seems that the included booster will direct thread with the 1/2x28 threads on the AP5-P. So I can at least enjoy it for a bit, but I am dead set on finding a tri-lug adapter. If any of you have experience with this system and could provide some advice it would be greatly appreciated.
