I've used the F2000 in the US (Scottsdale Gun Club has one you can rent), it's very similar to the AUG, I'm pretty confident FN had one nearby when they came up with it. It's just more bulky, I particularly don't like the forend and although there is a vertical foregrip available it's not as user-friendly as the one on the AUG. The only thing it really has over the AUG is that it is ambidextrous.
Even the trigger pull feels like an AUG, although it at least has a proper selector switch unlike the AUG.
So buy an AUG instead. Oh, right...
