Full brass cartridges act as "heat sinks" drawing a great deal of the heat out of the weapon with them. The brass alone would probably solve the problem (thanks to the lower rate of fire from these guns). Machineguns solve the problem by being "open bolt" weapons. By having the bolt back, air can circulate in the chamber to cool it. You do bring up a very valid point, especially regarding SAW's or automatic rifles. I have heard the Marine Corps M27 SAW (based on the H&K 416)can be equipped/is equipped(?) (someone will have to fact check me on whether the USMC guns actually have it) with a special bolt hold open (in addition to the normal hold open) that allows the shooter to lock the bolt back, but to fire the first round from an open bolt like a machinegun if needed. The fact that this feature even exists, is proof that these guns may suffer from overheating if fired too much.
