Are Threaded Barrels Legal in California?

Threaded barrels are generally illegal in California unless registered as a firearm with a legal suppressor or comply with strict state laws.

Threaded barrels are generally illegal in California unless they are part of a firearm registered with a legal suppressor or meet specific state requirements. You should understand California's strict gun laws before owning or modifying firearms with threaded barrels.

This article explains the legality of threaded barrels in California, how the law applies, and common mistakes to avoid. Knowing the rules helps you stay compliant and avoid serious penalties.

Understanding Threaded Barrels and Their Uses

A threaded barrel is a gun barrel with threads at the muzzle end. These threads allow you to attach accessories like suppressors or muzzle brakes. Many gun owners want threaded barrels for customization or noise reduction.

However, California treats threaded barrels carefully due to their connection to suppressors, which are heavily regulated. Knowing what a threaded barrel is and why it matters helps you follow the law.

  • A threaded barrel lets you screw on devices like silencers, which reduce gun noise and muzzle flash.

  • These barrels are common on pistols and rifles designed for tactical or sport shooting purposes.

  • California restricts threaded barrels because they can be used to attach illegal devices without proper permits.

  • Threaded barrels alone are not illegal, but their use and possession are tightly controlled under state law.

Understanding these basics helps you see why California regulates threaded barrels differently than other states.

California Gun Laws on Threaded Barrels

California law bans many firearm features that are legal elsewhere. Threaded barrels fall under this scrutiny because they can be used with suppressors, which are mostly illegal in the state.

The California Penal Code and the Department of Justice have clear rules about owning or selling firearms with threaded barrels. You must follow these rules strictly to avoid legal trouble.

  • Threaded barrels on handguns are generally prohibited unless the firearm is registered as an assault weapon with the DOJ.

  • Owning a threaded barrel without proper registration can lead to felony charges under California law.

  • Rifles with threaded barrels may be legal if they comply with California’s assault weapon restrictions and do not have other banned features.

  • Suppressors are illegal in California, so attaching one to a threaded barrel is a criminal offense.

Knowing these laws helps you avoid owning illegal firearms or parts that could cause serious legal problems.

Exceptions and Legal Ways to Own Threaded Barrels

There are limited exceptions where you can legally own a threaded barrel in California. These exceptions often involve registration and compliance with strict rules.

If you want a threaded barrel, you must ensure your firearm meets California’s legal standards and is properly registered if required.

  • You can own a threaded barrel if the firearm is registered as a legal assault weapon with the California DOJ.

  • Law enforcement officers and certain licensed individuals may have exceptions for threaded barrels.

  • Some rifles with threaded barrels are legal if they do not have other banned features like flash suppressors or pistol grips.

  • Always check with the California Department of Justice before purchasing or modifying firearms with threaded barrels.

Following these exceptions carefully is crucial to stay within the law and avoid penalties.
