The Firearms Section’s central mission is to provide high-quality, timely and cost-effective forensic examination, analysis and interpretation of firearms-related evidence.

That includes the function testing and firing of firearms, the examination of microscopic bullet and cartridge case evidence, the restoration of firearm serial numbers, and ballistic imaging to determine whether two or more firearm crimes are related. Firearms Section specialists also carry out ATF-approved training on the National Integrated Ballistic Information Network (NIBIN.) Examiners reach a finding from a range of conclusions. Since the Firearms Section began ballistic imaging in 1997, it has linked more than 3,000 crimes to others they were not previously known to be associated with, making it one of the most successful ballistic imaging centers in the world.
