It would be much more accurate to say the M-60 was a design based on the MG-42. But, that is just a pesky factoid in the fantasy world of the media.
“It would be much more accurate to say the M-60 was a design based on the MG-42...” [pfflier, post 68]
A bit of a stretch.
Both the M-60 and the MG42 were in concept general-purpose machine guns. But the M-60 is gas operated while the MG42 operated by short recoil. The M-60 uses a rotating bolt, but the MG42 uses a roller-locked bolt somewhat similar to HK’s G-3.
Both machine guns use push-through belt feeds. The M-60 uses a disintegrating link belt; the original MG42 used non-disintegrating link belts but later versions were adapted to us the American disintegrating links, when newer versions were adopted by the Bundeswehr.
