Which type of gun is prohibited from being entered into the NCIC?

The NCIC (National Crime Information Center) has specific guidelines on what types of firearms can be entered into its database. BB guns, which are typically classified as air guns that shoot projectiles at low velocities, do not fall under the same legal regulations and definitions as conventional firearms like rifles, handguns, or shotguns. Therefore, they are not included in the category of weapons that can be reported or tracked through the NCIC system.

The distinction primarily lies in the operational mechanism and the intended use of these weapons. Unlike traditional firearms that are subject to stricter laws and registration requirements, BB guns are generally considered to be toys or sporting equipment and not firearms in the legal sense. This is why they are explicitly excluded from NCIC entries, which are focused on tracking real firearms that pose a greater risk in terms of law enforcement and public safety concerns.
