A German newspaper has revealed that a Bundeswehr report has said that once the H&K G36 rifle has heated up, the accuracy is significantly reduced to a point where it is useless beyond 200 meters (218 yards). These are pretty serious allegations!
I expect H&K to respond shortly (or maybe they will just ignore the allegations and hope it means greater sales of the HK416). The XM8, a rifle derived from the G36, nearly became the US Army service rifle.
