My goodness, that is difficult to read. It is funny that it translated the name "Koch", but couldn't translate treffleistung.
It basically boils down to a lot of hype from someone expecting a weapon to fill a role for which it was never intended. The DI system in our M16/M4 is looked down upon, for the similar reasons. A sturmgewehr, or assault rifle (although I like storm rifle, and might start using that) makes trade-offs. One of them is a thinner profiled barrel for balance and total weight reduction, which means accuracy will degrade if the barrel is made to heat up a lot. The role of an assault rifle is not one that will suffer this problem, when used within established doctrine and training.
As an assault rifle, both the AR/M16/M4 and the G36 get the job done, and do it quite well (although I would prefer a G36, I would still carry an AR platform to battle without worry).
