SAW M249 5.56MM
M240G 7.62MM
That is the M240 that replaced the M60. It is a 22lb weapon with a firing rate so high that they had to put shock absorbers on the old M60 tripods so the weapon didn't flip over when firing. It's rate of fire is more like a WW2 German MG42. The funny thing about it he was so close the bullets were just melting the plastic so you didn't get the explosive power of the hits.
