They usually say 6-8 weeks. That's bumped up to 10(maybe 12?) recently. I've gotten lucky a couple of times and had them ship well below that time frame but those are definitely the exception. I put an order in the middle of Jul that was supposed to be 6-8 weeks. I emailed them last week and was told it'd be another 2 weeks.
Did you get one of the "immediately" rifles? If so, that should cut down your time considerably but I've also seen that it takes a couple of weeks to get the rifles in hand from the time they're "ready".
