All of the AKs I have seen have chrome bores. They can accommodate corrosive ammo without rusting. I have no clue what the brown stuff is. I would try contacting the manufacturer or distributor by e-mail and ask them.

I hate to tell you but not all AKs are chrome lined. Yugoslav M70s and a few others for the most part have never been and most of the American made barrels are not as well unless you spend a lot extra.

As far as lacquer melting well it does not truly melt but it gets gummy and sticky in full auto or major mag dumps and was mainly an issue with 5.56 and not 7.62x39.

The angle of the 5.56 chamber is much less than the 7.62 so after full auto/fast multiple mag dumps if a round was left in the chamber and allowed to cool the lacquer would stick to the chamber wall and act as glue then when fired it had an issue of ripping the case head off. I had it happen more than once back in the day.

That is the reason they went to the Teflon coating.

Even though AKs are gas piston and most of the gasses will be let out the front there still are some residual gasses and power dumped into the trigger group when the bolt opens and the empty case is extracted. So if you go and shoot a couple mags full or more you will most likely get some gunk dumped around the trigger group.

My guess it that is what your are seeing.

Big fan of Mack & Jack's African Amber here.

Somebody has been buying growlers at Fred Meyer's...
I love it too! LoL

I had this issue with my new guns too, just figured it was some crap from the factory. Seems to go away with a few cleanings... (fingers crossed)

It's not from the gun. I'm fairly certain it's coming from the wolf polyformance ammo now. I shot the same ammo from my micro draco and had the same brown residue

But I didn't shoot anything from my Ruger and had the same brown residue...
Took me like 15 patches to get it cleared...
Not to discredit, just saying.

Yeah I can dig it. Could also possibly be its 2 different things with similar appearances. Looks like the cosmoline I cleaned out of my wasr too, but its not. Who knows though. I wish I had a genius scientist friend who could run tests on it lol.
