RE: Best SkS?
I'll say this, There are NO "NICE YUGO SKS's" in the world...they're all cheap pieces of crap.
There are TWO decent/good makers of SKS's, Norinco (China) and Russia...there are a few Yugos, czechs, and other "land of twenty names" SKS's out there that are good, but it's just dumb luck that THAT ONE RIFLE is decent, on the whole they're crap. Norinco's and Russian SKS's are generally a bit better quality, but there's no guarantee.
I've had probably 14-16 SKS's of various makes, the only ones that I've "liked" have been the Russian and Chinese Screw bbls and ONE pin bbl Norinco that I've got that's a TACK DRIVER...
