Here's where the AUG failed from the getgo. I found (me and Toastmaster) that the AUG's hopup was strangely weak, as if even with .2's that they were traversing a much shorter distance than even a stock TM AEG which had less power and this was on full hopup. Dissasembling the hopup unit, we discovered that the spacer itself was too soft, and so we replaced ours and solved that problem easilly enough. Not such a problem, but something to note.
I think that's a fairly universal CA problem. Luckily a little less than $10 will get you new hop-up rubber that'll fix it.
