Maybe this will rub some people the wrong way, but I don't understand the obsession with painting full camouflage patterns on AEGs.
Judging from the footage and photos available today, it seems like the vast majority of soldiers in Iraq or Afghanistan do not paint their guns. For those who actually do it, it also looks more subtle than just spray painting their gun from stock to muzzle. Sometimes you can't even tell whether it's intentionnal camouflage or mud/dust.
