According to Wasserman-Schultz's office, the legislation would "close a loophole" that allows "criminals, domestic abusers, and dangerously mentally ill individuals" from purchasing ammo.
If passed, the legislation would require ammo purchases to undergo a background check through the National Instant Background Check System (NICS), the same system that is used to conduct background checks for firearms purchases.
Every retailer who sells ammo would be required to conduct a background check system through the NICS system, which isn't a problem for most gun stores who are federal firearms licensees (FFLs). The potential issue would be from stores who sell ammunition but not firearms and do not possess an FFL. They would either have to partner with an FFL to conduct the background checks or they would have to go through the process to become an FFL.
