You want "junk", try an Egyptian Maadi. Thick black paint finish that looks like it was put on with a 4" exterior house paint-brush.
If it 'runs' with a receiver & magazine full of sand, I'll ignore the paint job.
FWIW, if 'you want "quality" & "reliability," try a Hungarian AMD' (or an FAL, of course, if you want the best ;>)...

The finish isn't anything extra but no worse than most other AK-47's I have seen. The quality of the internal machining, fit, etc. was better than average.
I also have owned several Helwan's made by Maadi and they are the same. Plain finish but very well made overall. They also function perfectly and have proved better than most in accuracy. I still have one. The only thing I would down grade them on is the mags really don't look very good but they actually are ok.
