This is important! Need barrel thread info

Okay guys,

My Dad came up with an idea that I had never thought of and I will look up the info if no one has it here.

He has seen threaded Galil .223 barrels for $39.

What is the size and pitch of the Galil threads?

Do they follow the same as the Russian pattern? The Russians were sticklers for using the same tooling over and over. The Nagant is .980 16V T.P.I and it would stand that the SKS probably has that same size and maybe the original Russian threaded AK's.

Does the SKS have that thread size?

Did the Israeli's use the same thread pattern as the the Finns and Swedes for their versions of the AK.

If the Galil barrels are the same pattern then .223 AK's and SKS's could be made pretty easy.

Anyone able to fill in the blanks?

Damn! No one has these specs laying around in their vast firearms libraries? :D
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 and see if the ORF boys can give me the Galil stuff.
I got an answer on the Galil from Todd at ORF.

M 21 1.5

My Dad says it's 21 mm and 1.5 is 16 threads per inch.

No the same or similar as the Nangant. Does anyone know what the AK models are?

I truley appreciate the muzzle brake info also.

If only the barrel stub info was easier to get! Old bolt actions are easy as there are many books with that info and I have a good one, but the semi-auto stuff is impossible to find.
Good luck Cephus!

I've been looking for 2 weeks on the net so far for some source. Todd was the best I found yet at ORF.
No prob!

I hope her foot heals okay, that sounds nasty.
Now, does anyone know the SKS and threaded AK sizes?

Thanks SKS!
