I have looked into the possibility of making a modelgun version of the MG42. However, I would not use the full scale MG42 (Asahi or Shoei) I would make the smaller Cetme Ameli and use either the MGC or the Marushin 5.56x45 cartridges in it.
Markus is right, the action would have to be assisted with either gas or some other mechanical assist as the motion of pulling the cartridges out of a real belt would cause problems. Now, if the belts where made out of plastic, the effort to pull out cartridges from it would be far less and it might work better.
The gun itself might be far harder to make than any profit that might be made from it. So, I cannot see any belt fed modelguns ever being made by any manufacturer at this point. I would love to have one (as many of you would too) but, like the MP5 I seriously doubt it at this time. If I where independently wealthy I would tool up to make both the MP5 and try to make a functional belt fed modelgun line. But sadly, I am not rich.....
There is allot of motion inside of a real machinegun what with the bolt, the feed mechanism and the belt sliding back and forth there is allot of friction everywhere that just uses up any power that the caps could provide. If the bolt etc. where helped with external gas pressure then it might just function properly. As I alluded to earlier the links have to be made out of plastic or the friction would be far too much for any system to function correctly.
