HK are not denying the fault- just their liability for it. Basically HK says we gave you exactly what you asked for because it doesn't get that hot in central Europe and Afrika Korps part II was not really a thing at the time.
It is illustrative for those wondering why our rifle and pistol test specs are hundreds of pages and testing takes years.
