They are for suppressive fire more than anything else, and the rifling makes the barrels heat up to the point where they must be changed. How come machine guns aren't smoothbore?

Probably because of the friendly fire risk, when you have a platoon advancing you don't want bullets going in random directions.

youre talking nonsense, a machine gun is not restricted on barrel type. is is interchangable for both types but a smooth bore is more accurate and faster when shooting 325-1000 rpm. trust me i know guns

How can a smoth bore be more accurate? Isnt that the point of rifling?

The smoothbore wouldn't be more accurate, but machine guns don't need accuracy as much as other guns. However they often do have problems with barrels heating up, which would be caused in part by rifled barrels.

When you say " machine gun" you are refering to a Belt Fed Full aotomatic are you not?; because that is what a machine gun is. An AK-47 or M-16 is called a select fire sub cal. assult rifle. It can shoot full auto or semi auto ( one bullet per trigger pull ). Rifling is used in both because it makes it more accurate with higher velocity at a longer range. Rifling also determines the angle of yaw when the bullet hits soft tissue. Machine guns are not always used as spray and pray weapons. They were also used as sniper weapons with good accuracy: however no where near as accurate as a bold action.

By machine gun I do mean a belt fed weapon and not an assault rifle. I differentiate between the two.

I believe that machine guns do need to be accurate and therefore rifled or the military would not make them so, I don't know of any smooth bore machine guns, if so wouldn't they be called musket machine guns? Maybe rifling on machine guns are just a happy medium between spray & pray and longer range accuracy? I don't know. Maybe the gun expert would know. I don't know if airplane 20mm or 37mm cannon guns are smooth bore either.
