I've been filming action adventure movies for 5 years now, and I have a vast assort ment of mock arsenal. I get most of my guns from random airsoft sites, but I found the best for prop guns is MFI airsoft. http://www.mfiap.com/airsoft/main_air.htm I;m not sure if they ship to down under, but it's worth a gander.(posted 8019 days ago)
