Honestly if you're going to be using it specifically for CQB, and you're keen on an AK, you might wanna look into a AKS-74U. The Guarder conversion is ludicrously expensive, but the VFC (GB-Tech) AKS-74UN is priced quite nicely for an all metal gun, and being in the US you could easily pick one up from Airsoft Extreme, or AirSplat, or a number of other retailers.
