Hello,
I probably first stumbled across this website after discovering the existence of the M59 (though I'm sure I've stumbled across it before). I came across a listing online, thought it was mislabeled (since it has not grenade launcher, etc). But then I realized it was real. Since then, I've come to realize there doesn't seem to be a whole lot of information out there about; but most of what you need here. I own a few and figured this would be a great place and share and learn more about the various SKSs; so here I am!
