moderator thread?

hi, what is the thread on the air force talon ss/gunpower stealth’s moderator that screws into the barrel. i want to get an adaptor that changes the thread down to 1/2 inch UNF so i can try out new moderators as i think the standard 6 inch with the 3 inch add on moderators that im using just now are crap as they have no baffle’s or anything inside them to catch that horrid sound! help?

thanks mark
