First Gun

I am about to buy a new airsoft gun. My first airsoft gun. Because I am a member of an airsoft team that portrays the eastern Russian Spetsnaz (special forces a bit like SWAT), The guns I can buy are limited to modern versions of the AK. There are some phenomenal guns out there, but the best ones are extremely expensive (around 400$) and I don't have that kind of money. So I have been doing a great deal of research to find a good balance. Two main candidates I have found are the CYMA CM031 AK-74 Ver. 2 and (this one seems to be the best) the CYMA CM036 Full Metal AKM. The reviews are good in general and I like the look. If necessary I can upgrade the AKM to be an AK-74 and the quality seems good. The only problems I have heard are that the plastic grip and forward grip are cheap. I plan on replacing these with the real thing. I should be buying the AKM soon.
