Hi Mate,
The owners manual was one of many things the importer to the USA didnt get right. There IS an owners manual, and I am soon to be getting hold of a soft copy to put up on the internet. I've spoken at length with AIA and they literally are up to their eyeballs in orders and struggle to meet demand with their small production facility. I'm told this is changing for the better, but I dont have any specifics. This is one of the reasons its difficult to get responses to emails - they're too busy making rifles. BUT, they acknowledge thats no excuse, and have asked me to extend their apologies to anyone I come across that has had communications difficulties.
Anyway, I will make a note to PM you with the URL for the manual when its ready.
If you're interested, and on facebook, there's a group for AIA owners as well - just search for 'Australian International Arms' and you should find it.
