The M-60`s we had, had a very harsh irritating staccato roar. Where as the 50 BMG`s at a distance had a restful comforting sound. A sound that to me said IMHO we have everything under control now, so you and yours can sleep much easier tonight. The 50 BMG`s were always very special to me, something that you could always put your trust in. And to tell you the truth that was something very hard to find in a hostile environment.
