Thread Fx Barrel Attachment .30

[Enkey]

Hi
Could someone tell me what the thread size of part number 19963 is, it is the cap that joins the transfer port with the coating of the 30cal STX liner, I am interested in the barrel side
Regards

1/2-20 I believe. the metal outer that the liner lives in, is threaded the same on both ends to make assembly easier. meaning there is no front or rear to the metal barrel liner housing.
