The milled ones all had thread protectors. Many, but not all stamped Chinese guns were not threaded. GARY.

Yes sorry I should've been more specific. Was implying if the OP had a correct diameter muzzle and it had the other requisite markings of an "original" mak90 (1st gen Mak90/B West model?) it may be to their pleasant surprise that after making it compliant they would find factory threading hidden underneath. A little gift that's been waiting 30+ years to be found

My barrel looks kind of strange. The entire barrel has very fine threading front to back. No thread protector, offset device, no nothing except front site.

For a MAK 90, I'd say that's not threading, just machining marks. Those didn't come with the smoothest machining where you ended up with a nice polished barrel so it actually does look like threading, but they're concentric circles, not slanted the way threads would be. At least that's how mine was.

Mine too. GARY.
