The effective range of the M-60 is 1200 yards. 5000ft is 1600 + yards. Then you have to take into account the effect of the rotorwash and the wind caused by the moving aircraft. All of this with a suppression weapon.
Before you go any further, I was a US Army helo Crew Chief/Door Gunner and used the M-60.
Take your "No shit there I was..." story somewhere else.

The Gulf of Tonkin is the body of water off the North Vietnam coast, it doesn't extend down to northern South Vietnam.
I was also a Crew Chief/ doorgunner in Vietnam.
