No, no paint. I might buy camo scope cover. I've never seen black R/S PSO1 before. One I have have is R/S, not Guarder repro, so I'll just leave it the way it is.
ancorp, I'm pretty sure Guarder steel bolt goes back and forth just like a real thing. Btw, from what I remember it looked like bolt on real AK didn't go as far as G&G's bolt. I could be wrong though, haven't fired AK's since 1998.
