CQB barrel for AUG

[st0rmforce]

An idea I've had for a while.
Seeing as the whole barrel assembly in the AUG can be removed without tools, could I put together an entire new shorter barrel? I love the long barrel in woodland where range is needed, but it's a bit awkward indoors and its too hot as well. I'd love to take it to my local urban site...

The biggest problem is getting the bits. The inner barrel and hop are easy, it's just everything else I can't find anywhere.

Anybody know where I could get hold of large spares for an AUG?
