Good questions. According to the Sako 2020 Catalogue
We take great pride in our work. Each rifle is carefully assembled by a single person, and each individual barrel is visually inspected. Every rifle goes through manual accuracy testing to ensure it can perform under 1MOA accuracy and is delivered with a certification that guarantees its quality and accuracy.
I guess the S/N can be used to identify the assembler. Did the gun come with the quality and accuracy certificate?
