I posted some info and pics over at AKfiles, but since this is more the forum for specialists (IMHO), I thought I'd drop my questions over here too. Want to know more about this... somewhere I read that Bulgy AK-105s often have Tula-made, not marked, trunnions with a '4' barrel journal...my trunnion has the '4' also.

What are my options for barrels and how do I read the Bulgy barrel I have?

It's interesting that this kit (from KVAR) is a (30) year code, (that is 1990 right?... 30+60)... the first batch, the barreled Bulgy AKS-74 kits I saw had all been (31), granted these other kits all came in one batch from one vendor, IIRC. But now we know that the Bulgys started earlier than 1991... any info on other Tula parts, or Izzy parts for that matter, that might have been brought down from Mother Russia? Any reason for the timing 1989-90? If Bulgaria had already been making these for 2 years why the need for Russian parts? Also, I know my kit comes with a probable Tula folding stock (rolled struts and ribbed buttplate)... and a Tula trunnion... any way to determine if any other parts are Tula? (from mold number format etc?). The paint on the trunnion gives the Tula trunnion quite a different look. It doesnt appear to have been parked before paint; I read that this is a feature of Tula parts. I am assuming there is no chance that some of these where made up in Tula and sent to Bulgaria-land (like the Tula Maadi AKMs).

Thoughts, comments, and pics (of anything related) would be much appreciated!!!

This is my Bulgy 74 barrel. Am I looking at a (2 2 2 0) or a (4 0 3 4)?

The owner of Arsenal Inc. gave me some insight on this. Russia had sent a large amount of parts to Bulgaria with plenty left over after Bulgaria began producing everything themselves. Workers would take whichever parts were available to assemble the guns. Either worked fine so they didn't care.

The vertical string is the journal sizes front to back. The horizontal number is the barrel ID.

Does anyone know if/where the Bulgy's might have stamped journal sizes on their AK74 trunnions. Is it easier to just measure with a caliper?
