The conception of the M60 was pretty darn similar to the FG42, the T44's design was notably close to that of the FG42. :P (Sorry for being a tad repetitive there) I wouldn't know about the internal schematics though. And I said practically, not 100%. (Otherwise, it's just a little more than only the firing mechanism)
