Its an STG 2000 which is basically a Romanian AK with a stock made to look like an East German Weiger rifle. IO has been making these in 7.62x39 and .223 for a while now. I have several AK's and this rifle while nothing special it still a solid Romanian based AK but mechanically not really different from an other WASR AK. If you want an AK that has a little different look thats what you get. but performance is the same as any other basic AK. If you want a high quality built AK look at Lancaster Arms or Arsenal.
Here is a site with more info.
