Tell you what gentlemen, it is no easy task to find the measurements I seek.
No one has a firearms book with barrel thread measurements? I really don't want to take my SKS apart to find out if it is same as the Nangants.
I do have a book, but it only gives bolt action rifles that were popular.
Next I'll post over at AK47.net and see if the ORF boys can give me the Galil stuff.
