Ok I already knew all that, that it is easier for retailer to import clear or tinted one, because full metal don't pass the custom. So I think that I need to be clearer then with my question
Should I be worry buying a cansoft with lower plastic receiver that it will break easily. Let say that you trip and fall on your gun, on a plastic lower receiver one. Is there some good chance that it can crack or I would have to fall on it and on a rock etc...before it can crack.
That's what I need to know.
