I have always lived in CT. The AZ thing is a get-this-account-going-now mistake.
The rifle is a post-ban rifle that I purchase at Newington Gun shop in CT (new) approximately five or six years ago. In CT, the assault rifle ban has never lapsed. People with pre-ban stuff can't sell it in this state; they have to go to more reasonable states like AZ to sell it.
I'm not sure what else to say. I haven't used it much. It's fun, but the nearest public range that doesn't require a membership is 45 minutes away - in the wrong direction.
