Yes, gun silencers are certainly illegal in many places. In the United States, for example, it is illegal to possess or manufacture a silencer without a special license from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Violation of this law is a federal felony punishable by up to 10 years in prison. Similarly, in Canada, it is illegal to possess or use a firearm silencer without a valid firearms license. Penalties for breaking this law can include up to 10 years in prison. Other countries have similar laws banning gun silencers.
