Not an SKS...but milsurps none the less.. 3 come to mind if one wants accuracy in a vintage military rifle made outside the US.. largely because these nations have a history in shooting sports, a Swiss K31, a Swedish M96 or a Finnish M39. Owning several variants of all 3, I can say they will best any SKS, Ak or Vz I have, to the point of almost being mildly boring to shoot at 100 yards. They beg to stretch out to distances where the SKS, Ak and Vz are running out of wind.
But, GM, that's comparing apples to oranges,..a full size cartridge vs an intermediate size cartridge, bolt vs. semi auto, longer sight radius, marginally better sights.. I know this, but there are better choices for roughly the same money if accuracy is the prime objective.
