Why is heat a problem? Full auto MG's with linked belts of 250 rounds deal with it. On a burst fire infantry weapon, that's been dealt with by holding the bolt back and leaving the chamber open.

Colt already has a prototype that fires close and open bolt, when it hits a predetermined temp it switches over on it's own. Submachine guns mostly fire open bolt.

Worried about the bolt chambering and moving the sight picture? The LSAT uses a shuttle bolt that reciprocates vertically, and the mechanism isn't high mass.

Since there's already video of LSAT's firing full auto with 100 round belts on youtube, I think the engineers were more than aware of the heat sinking and addressed it. Is it being said they're a bunch of morons and don't have a clue?
