I'm Sure They Were Just Using it Wrong
The Firearm Blog has a report about allegations that the H und K G36 doesn't perform well once the barrel heats up. For those who don't know the H und K G36 is Germany's standard issue infantry rifle. Apparently the rifle is unable to accurately hit targets past 200 yards when the barrel gets toasty, a rather worrisome problem. Well, it's a worrisome problem until you realize the weapon is made by none other than Heckler and Koch, who are the peddlers of high prices weaponry that is desired by mall ninjas the world over because H und K doesn't like civilians.
Knowing H und K they will probably send out a press release regarding this issue that merely states "You're using the rifle incorrectly." I also expect H und K fanboys to make numerous excuses about why this isn't actually a problem. If there is one group of firearm fanboys more zealous than the 1911 crowd it's the H und K crowd. It is an understandable zeal, after all H und K firearms appear in every Rainbow Six game.
