I have mixed opinions when it comes to Russian products. Quality wise they usually seem to be pretty good, (with the exception of some stuff produced at the height of WW2), and they tend to be extremely rugged. Ergonomics wise, they really suck. Whether it's Mosin safeties or crazy offset scopes that make cheek or even chin welds impossible, there just seems to be no concept of human engineering. Now if they were copying an American product, I'd be interested, but from what I've seen the Russians aren't particularly into copying others products. I'm sure they have done it in the past, but building cheap copies of others innovations seems to be more a specialty of the Chinese.
As far as it being unAmerican? Why would it be any worse than buying a Saiga? It's just a gun.
