Looking at new airsoft gun, KWA KG36 Commando (2nd Gen)?

I think you just have some unlucky friends or they are at fault for the problems. KWA pretty much is the all around BEST airsoft company on the market now. There excellent externals and unmatched internals put them there. There G36 series is an excellent series too. A friend own one and loves it and has no problems. So yes, the KWA G36 Commando is an excellent route to take. The only other brands I would recommend that make a G36 would be ARES (H&K) and Echo 1, but I still think KWA is even better than those.
