I googled a bit and skimmed some blogs and forums.

The temperature problem arises after the third cartridge has been emptied in ongoing single shot scenarios. The weapon then creates a spread of 1.20 meters at 100 meters distance. Do not know if that is much or little, I have no expereince with these things.

The rifle is said to have a very good manufacturing quality and very good sights, but the precision beyond 200-300 meters in general suffers due to the light-weighted ammunition the BW fields for it.

The problem of heated weapons seems to be focussed not on the barrel itself, but due to the fact that while the barrel is metal, major parts of the frame are made of polymer components. Heat from the barrel cannot be transported away from the barrel into other metal parts, the plastic in parts block that heat transportation, or does not transport it as good as metal. Some people referred to other weapons made with plenty of plastic and used in foreign militaries also suffer from heat transportation problems.

It seems to be that the more plastic is used, the more problems with heat show up. An assault rifle certainly is not to be used like a LMG or MMG, however, that you need to fire two or three magazines in single fire when being in a war is something one should take into account as a possible and likely scenario.

I also found media reports quoting H&K that long lasting firefights were never a design criterion for the weapon.
