Before applying for an FFL, you should make sure you and your business are eligible. If you meet the requirements for an FFL, the ATF is obligated to provide you with a license. The FFL is a “shall issue” license rather than “may issue,” meaning the ATF has to give a license to everyone who qualifies.
It’s also worth noting that you must have solid business intent, even if you don’t consider your store an official gun store. Before applying for an FFL, your business must already be formed properly and registered with your state. Alongside that, you must consider other FFL requirements.
