Here in Canadaicon, I know things can get really confusing with the 'non military' 03's. More than one gunsmith has told me stories of counterfeit star gauged barrels & NRA target rifles being built to spec... I think that's why I'm not so worked up on pedigree. If the rifle was properly papered, odds are I could not afford it, or at least not the number I have now. My interest at this time is to have a 'correct as possible' collection. If its a rifle I assemble, I will try to use a tell tale mark if it uses aftermarket pieces. But I'll still try to put it together correctly.
