man my aa was soo awesome look what it decided to do to me.... (for those of you who can't tell by the pic i was unscrewing my barrel and the epoxy came off and i got two barrels YAY!!!! *sarcasticly*)
Wow, that's pretty strange lol... How old is that barrel? I've heard of the older ones doing that (rare though), but never any of the new ones. My AA shoots great with medium bore paint (pro ball platinum namely)... Nice and quiet, but not too gas efficient.
