well IIRC it was the bolt shape which was used to regulate rate of fire of MG42 as per why to lower it you yourself pointed out that the metal may not be up to the standards to withstand high rate of fire so by lowering it you wont make barrel too hot, and with a quick barrel change you may have a workable weapon system.
You might be interested in watching this You Tube video: https://www.youtube.com/watch?v=zh8lDgV993A It shows the firing of an 850 round burst out of an M60E4. Barrel technology moves on. But I wouldn't want to touch the thing just afterward.
been there and done that on C6, and had a second degree burns on palm of my right hand to prove it. But we had 6 ammo boxes likned together. As per ammo links I think it would be an easy task to make a die and have a pneumatic stumping machine making links by hundreds per minute as the steel doesn't have to be top quality
I have to agree that you could do all this. But why bother when other designs are simpler to make and work quite well?
