Destructive device
A destructive device is a firearm or explosive device that is regulated by the National Firearms Act of 1934. Examples of destructive devices are grenades, firearms with a bore over one half of an inch, and certain semi-automatic (one cartridge is fired for each pull of the trigger) shotguns. Regulating an item as a destructive device effectively limits the item to the military and law enforcement officers only, except in certain circumstances.
While current federal laws allow destructive devices, many states have banned them from transfer to civilians, and only law enforcement officers and military officers are allowed to own them.
All National Firearms Act items, including destructive devices, must be registered with the BATFE, who then closely monitor use, transport, and storage of the items.
