A firearm is generally a rifle, pistol, shotgun, or other portable weapon that expels a projectile (bullet) by use of an explosive action. The definition of a firearm may vary from state to state under state statutes—and under federal statutes—and related items such as a muffler or silencer may be included in the definition of a firearm for purposes of certain criminal offenses (crimes).
In Nebraska, a firearm is defined under state law as any weapon that is designed, made, or adapted to expel a projectile through the barrel by the action of an explosive, or any device readily convertible to such a use. This includes rifles, shotguns, and pistols. Nebraska law aligns with federal definitions to some extent, particularly in the context of criminal offenses where the use or possession of a firearm is a factor. Additionally, items such as silencers are regulated under both state and federal law. Under the National Firearms Act (NFA), silencers are considered firearms and require registration. Nebraska state law also requires individuals to adhere to federal regulations regarding silencers and other firearm accessories. It's important to note that both state and federal laws include specific provisions and exceptions, and the definition of a firearm may be interpreted differently depending on the context of the law or the specific criminal offense in question.
