I have a 4 digit Chinese SKS I got from the first Classic batch back in 2013. Finally tried it out a year and a half ago. At 100 yards it spewed 10 rounds into a basketball sized group about 8 or 10 inches low and right. I think the horrible trigger might be involved.
I also have a Maadi AK that shoots about the same.
