Just out of curiosity does anyone know if an NFA check follows the same procedures as security clearance and credential checks?

I know that for clearances and creds, which are often redundant. They basically look from "today" back to your last check. So for me they would be looking at the last 6 months and I would get a check back much faster than a guy who is a first timer or a decade out.

Just a random thought about one of the apparent disparity in approval turnaround. Although it really should be electronic and nearly instant in this day and age.
