The National Firearms Act (NFA) was enacted in 1934 in the United States to regulate certain types of firearms and devices. It imposes strict controls on items such as machine guns, silencers, and short-barreled rifles. The law requires individuals to register these items and pay a tax, aiming to reduce crime and promote public safety. Under the NFA, firearms classified as "NFA firearms" must be registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Failure to comply with the NFA can result in severe penalties, including fines and imprisonment. The act remains a significant part of U.S. gun legislation today.
