Curiously, there's no waiting time on the AR-15's and M-16's being smuggled into the USA from Iraq. I don't have one, but someone I know does and I'm normally not a scofflaw but I celebrate these patriots who are taking risks to make sure they have arms just in case we see UK or Australia type seizures soon.
Picked up a S&W MP15 last week. Now stocking up on ammo and waiting for the call. My gun shop gets a few every week and they were selling out in a day or two. But since deer season ended they have less traffic and there is always 2 or 3 on the shelf all the time. No backlog here unless you want a specific model.
