No, it wasn’t the M60 is a gas-operated, rotating bolt weapon, uses disintegrating belts, closer to the Lewis Gun in design.
The MG42 is a roller-locked recoil-operated gun with nondisintegrating belts. Different in every respect.
"The M60 machine gun began development in the late 1940s as a program for a new, lighter 7.62 mm machine gun. It was partly derived from German guns of World War II (most notably the FG 42 and the MG 42),but it contained American innovations as well. Early prototypes, notably the T52 and T161 bore a close resemblance to both the M1941 Johnson machine gun and the FG 42."
I was told the same thing when I was in the Army.
