Specifically the reason I want 2014 FTW's for this is because the problem isn't the first set of guns they built, it's their current guns. Can't judge a company based on their first line of guns.
I still want to take apart a 3.0 motor, haven't heard good things about them so far.
Except you don't forge pot metal into a billet, then machine it, you might as well spend the extra for real metal for the amount of machining required lol
It's also far more cost effective to cast and machine. A more correct saying is; "CNC" in the airsoft world, means a CNC machine once performed some sort of operation on the cast part.
Even with high quality castings that have been machined, there are always tell tale signs of it being a casting. Like systema for example, when someone breaks an upper receiver, there's usually some anodized black spots on the broken side of the receiver tabs, those are casting cracks from uneven cooling.
With FCC, the most notable faults are where they machined through the wall between the mag well and mechbox areas. In a casting that's to proper size, like systema, you wouldn't get that break through.
Unfortunately, but fortunately, nobody's broken an FCC receiver yet to inspect that. It's not often someone spear throws a ptw anyway, let alone an ftw.
