Anyone know what the thread size and pitch are on the 9mm 16" uppers are? I'm looking for a replacement muzze device, so I need to know the exact numbers. No guesses or "I think...."

For what it's worth, I bought this new from Atlantic Firearms.

go to the rimfire & pistol forum

it should be there somewhere.

iirc it was something like 1/2x 36 or something like that but dont quote me on it.
