Mike, I don't think the contempt is for investment casting as much for the failure to clean up the casting, to remove the mold marks. With todays CNC equipment you are talking about seconds, not hours of work. Plastic stuff has mold marks, guns should have light machining or a hand file to remove them. The problem with this gun and all the Rugers is that they eliminate all the non essential finishing steps as a cost containment. When you pull the stock off your internal parts just look half finished. Do they work, yes. But do they compare to the internal parts of even a modern Remington 1100, no. And for a "fine" gun that is a low standard to not meet.
