Doing a quick google and the GCIC is the georgia and the NCIC is the FBI, each check at a different level state v fed.
Although NICS is administered through the FBI, too, and it contains more than either of the two mentioned.
What I am getting at is...when a background check is done for the GFL is it advantageous to have the FBI do the background check when a NICS check done locally would bring back the same information? edit: so a NICS check is better than the FBI background check or the other way around?
No, it is not "advantageous." It is absolutely redundant. A waste of time and energy. It is also not required for the license exemption from NICS at point of purchase. As for whether a NICS check is "better," it depends on how you look at it. The NICS database contains more information than does NCIC. Is that what you mean?
From what I understand, the NICS check is more thorough than an FBI print check, which is more thorough than a GCIC print check. I'm sure someone can correct me if this is wrong.
