Yeah, WE GBBRs are pretty great, most of the time. A whole other level from their pistols, haha.
As for the AK, a quick search through the forums brings up threads like this:

CYMA AKs (CM 04x models specifically) with a full stock are supposed to be decent entry AKs.
As always, it's recommended that you save a little bit off one more pay cheque, and buy higher quality - get an LCT.
Apparently Real Sword is producing their Type 97s again, so you might be able to get your hands on one of those, too.
Probably best to revive another thread about this, rather than hijack this one.
Also, you should remove the link to buying the gun, since this is outside the age verified area, and it's against the rules.
