I have held a Curios and Relics FFL since the 1990s and was due to renew it for another 3-year period. I sent in my renewal application on October 17th and received my new license on November 2nd. To be quite frank, I was amazed that ATF's Federal Firearms Licensing Center turned this renewal around so quickly.
I have criticized the ATF strongly over Project Gunwalker and the agency's management. However, I believe in giving kudos where they are due and the Federal Firearms Licensing Center turned my renewal application around in record time.
On a side note, if you have an interest in older military firearms or in historic firearms, you really should investigate getting a Curios and Relics FFL. It costs $30 for a 3-year period and allows you to receive eligible firearms directly. The golden days of being a cruffler may be fading but there are still some good deals to be had. Moreover, companies like Midway USA and Brownells will give you a dealer discount on purchases which pays for the C&R FFL if you order just a few things. It is something to think about.
