OK. Gotta put my .02 in. Armorer, US Army, 86-88. Broke the record at Ft. Jackson Supply School for M60 dis/reassembly. My reward was to hold it out at arms length until the last student was done.
The 60 had some good features, and two very bad ones. No other MG has to have the gas system cap
wired on. And if the gas piston is reinserted backwards, it becomes a very heavy straight-pull action rifle.
I had to fix a bunch that another Armorer did exactly that to.
I liked the SAW's, but Jeff White has already pointed out the differences in the missions, and the inadequacy of the 5.56mm for GPMG use. I agree. I got out before the M240B's were fielded, so I can't comment on them personally.
I preferred to fire the 60 off the shoulder, but I am big enough to do so, not all troops are. I found short bursts to be quite devastating fired as such.
Jeff22, I agree with OEF_VET, you should have learned to maintain the M2's yourself. Setting the headspace on them isn't hard, and hey, you'd have got to fire them.
The M60 is a decent GPMG, Kokalis aside, when properly maintained and serviced. It is just a total PITA to do so. I carried one whenever possible, but not every soldier is an Armorer.
