The Norinco I have used has functioned fine but the accuracy was pretty bad. Some love it some hate it. Out of my AR with an Eotech my Norinco groups were twice the size of AE groups. I'm not going for precision shooting here but 3.5-4 MOA is a sloppy for me. I have not tried Wolf or Barnaul ammo yet and would like to know how it compares to Norinco and American ammo.
