The M-60 has had a few problems, but has been well-recieved in spite of them. Originally, it was said the M-60 was an updated version of the MG-42 (I WISH), but that was pretty much limited to the fact that it was stamped.
An interesting point about the M-60--you notice how no other Army has snapped them up? I think only Australian actually bought any in anything other than token numbersl, and those were replace long ago by the FN-MAG (240). Of course, I don't think the Aussies were keen to give up their BRENs.
I recall something quirky about the way the belt had to be loaded and the sear/pistol grip area was a bit flimsy. The bipod is actually mounted onto the barre--which could be changed fairly easy, if 20 years of memory serves me correctly. Wow, 20 years ago...and they were old then.
All that aside, I don't think I ever saw a stoppage or a runaway. That's a whole lot more than I can say about the M-16.
(I think the cone of fire was a bit tight too? Probably due to the bipod near the muzzle.)
I'm not real sure why we don't use MG-3s. (MG-42 in 7.62)
