Doesn’t the M-60 come with a quick change barrel?
The problem is that all the extras make the soldier’s load much heavier, until they destroy their knees and feet attempting to carry it all!
An M-60 can would probably weigh 5 lbs!

Yes it does.
While I believe you could build a lighter suppressed barrel system for the 60 it would still have the same problem with heat build up.
