Springfield seems to be clearly saying it's all US made.
You have to check criteria for "Made in USA" as it pertains to guns. I bet the standard is much lower then cars, for example.
Not much to debate. If a receiver/frame is greater than 80% complete it's a firearm and the ATF requires a serial number, manufacturer, and country of origin.
It's possible and maybe even likely that Springfield is outsourcing the forgings and a certain level of machine work, but if "Made in the USA" is on the firearm then most and the bulk of the important work was done here.
