If anyone ever considers buying a rare Model 70 from Dave Riffle I would recommend a polygraph test on him first to make sure it wasn't put together from parts.
I don't know about Dave Riffle, but I would look at that type of activity the same way I view putting together 03 Springfields out of parts. As long as the numbers match up, and the parts are "correct", what's the problem?
Seriously? A "rare" rifle from parts?
You can have it.
