Conditional: Suppressors are legal in Montana, where simply possessing one is not a crime.
Suppressors are legal in Montana, where simply possessing one is not a crime.

Suppressors registered under the federal National Firearms Act (NFA) are lawful, and hunting with sound-reduction devices is allowed.
