David,
Form 1?
First, thanks to Bush, you can't legally manufacture a selective fire weapon unless its for law enforcement, the military or overseas sale.
If you were a Class II manufacturer, then it is irrelevant as to the date of the receiver. Any other questions may be directed to our close and dear friends from ATF (remember, they're from Washington and they're here to help). Toll free #1-800-283-4867.
