If I could speak to the question of the cheapness of the weapon for a moment, I'd like to raise a couple of points.
First, why is it assumed that a "plastic" stock is cheaper than a wooden stock? I realize it probably is, if only a little, but if you look around, you can easily find some very cheap (meaning they don't cost a lot and nothing more) wood stocks. Some Marlin models come with "hardwood" stocks and some Rugers have rather plain stocks. Good wood doesn't grow on trees, you know, especially in China. Besides, wood stocks bring their own problems.
The other point is that it is probably going to be problematic to have wood furniture on a bullpup action, although it has certainly been done. Not a bullpup, but I believe I've seen photos of (original) AR-10s with wood forearms and butts.
