During this process, FTCB conducts research to classify the recovered firearms within the scope of federal laws and regulations. FTCB provides technical support and guidance through technical reports on aspects of the Gun Control Act of 1968, the National Firearms Act of 1934, the Arms Export Control Act of 1976, and other federal laws and regulations submitted as evidence in judicial proceedings.
FATD’s Firearms Technology Industry Services Branch (FTISB) is responsible for providing firearm industry-related technical support regarding firearms laws, regulations, and technology issues. FTISB issues marking variances to licensed manufacturers and importers to help them stay in compliance with federal laws. FTISB also issues curio and relic determinations for firearms that are novel, rare, bizarre or associated with a significant historical figure, period or event. Their specialists participate in congressional hearings and task forces, and serve as technical firearms analysis experts for proposed firearms legislation.
The Advanced Firearms and Interstate Nexus Branch (AFINB) supports ATF’s enforcement programs by providing high quality firearms and ammunition education training to ATF special agents and other law enforcement partners on weapon identification protocols and processes. This branch also maintains the National Firearms Collection, a technical firearms and ammunition collection that houses more than 12,000 firearms. These firearms are used as a reference to identify crime guns and weapons that are imported illegally, otherwise known as gun trafficking.
Combating Violent Crime
To make our communities safer, FATD staff use their extensive knowledge to help accurately classify crime guns and build a strong legal case against violent criminals. FATD also works with firearm manufacturers and importers to ensure that weapons are not illegally imported into the United States. FATD’s expertise helps to protect communities by providing technically sound testimony during judicial proceedings, which can lead to the incarceration of violent criminals.
