Open
Open means those non-canceled transactions where the FFL has not been notified of the final determination. In cases of open responses, the NICS continues researching potentially prohibiting records regarding the transferee and, if definitive information is obtained, communicates to the FFL the final determination that the check resulted in a proceed or a deny. An open response does not prohibit an FFL from transferring a firearm after three business days have elapsed since the FFL provided to the system the identifying information about the prospective transferee.
