Those wood stocks look great. Accuracy should be 3" to 4" with Norinco surplus. Many of us on this board are chasing small groups with various success. I've heard of some folks getting consistent 1" groups but have never seen it in person. My rifle just shot its first sub-MOA group with reloads but I think this was a fluke.
I found that barrel temperature has a huge impact. Mine shoots best hot and dirty.
Enjoy your rifle, tweaking is half the fun.
Mine was getting 1" groupings @ 100 yards with the 20rnd Norinco Green Box from marstar. The bulk norinco stuff is a different story...
