Manufacture of the Swiss StG 57 rifle

Interesting video, made (presumably) sometime in the 1960's/70's. I note that there are multiple steps in the barrel straightening process. With modern processes, would this still be the case?

Nice video. There is a similar one for the G3 in the rifle forum.

That barrel straightening process is pretty advanced, I watched a video from FN where they were literally dropping barrels into a length of vertical pipe and hand bending corrections. I was stunned by how low tech and lacking in precision it was.
