Quick question for small arms buffs

[daferg]

I know my guys in Iraq were glad they were not humping a 50 around. I am biased on the M240B because I had two of them and loved them very much. I have only heard stories on the G3 but from what I heard it is a fine weapon.

The Germans of WW2 might have been mean bastards but they made some fine weapons. I wonder why there was never a 50 cal? Granted, they did use the 20mm to their advantage but there was nothing between the 7.92 and 20mm.
