I looked at two arsenals and to be honest the Century m70 looked to me like it was made as well or better. I'm sure I will open up a can on that statement. But to be honest for a little cheaper, I went with the m70 and it just looks meand as crap. Each to their own but I think th m70 is one of the finest built guns century has ever produced. Also the barrell on the m70 isn't chrome lined which some say makes it more accurate.
I can't back up this statement but by father has a Norinco underfold and my m70 seems built just as well. But this is only my opinion. The only downside for some is I wouldn't shoot surplus corrosive ammo out of the m70 due to the lack of chrome lining on the Yugo models.
