"ALL OF THE ABOVE". Numerous posts (including mine!) and websites discussing the reasons why the bullpup design exists. Remember guys "form follows function". You don't get a bunch of weapons designers sitting around the salon saying "oh Stephan I wish we could make a gun that looks FABULOUS - but first, more gel for your FABULOUS hair"! It is a telling point that there are so many bullpup designs adopted by countries as their nation's choice for their main battle implement.
The reason THIS bullpup is so interesting is that it has been around for 10 years and can actually say it has been "battle proven". Whatever that means... that phrase seems to make it get a stamp of approval that it really does work. Or something.
