Are Binary Triggers Legal in Tennessee?

Binary triggers, devices that allow a firearm to fire one round on the pull and one on the release of the trigger, have gained attention among gun enthusiasts. In Tennessee, the legality of binary triggers is nuanced and depends on specific federal and state regulations.

While Tennessee generally permits the ownership and use of binary triggers, certain conditions and restrictions apply. State law controls firearm accessories like binary triggers, even though federal laws also play a role in regulating these devices.

Is It Legal to Own or Use Binary Triggers in Tennessee?

Yes, binary triggers are generally legal to own and use in Tennessee for residents and visitors alike.

• Ownership and use of binary triggers are permitted without a state license or permit.

• They are legal for sale and transfer within Tennessee, subject to federal regulations.

• Use is allowed on private property and most public shooting ranges.

• Manufacturing binary triggers for personal use is legal under state law.

However, legality depends on compliance with federal laws, especially regarding machine gun classification.

What Does Tennessee State Law Say About Binary Triggers?

Tennessee law does not explicitly regulate binary triggers but governs firearm accessories broadly.

• State law permits possession and sale of firearm parts unless federally prohibited.

• No specific Tennessee statute bans binary triggers or similar devices.

• Enforcement focuses on compliance with federal definitions of machine guns.

• Local jurisdictions generally follow state law without additional restrictions.

Thus, Tennessee law allows binary triggers unless federal law prohibits them.

Does Federal Law Affect the Legality of Binary Triggers in Tennessee?

Yes, federal law plays a critical role in regulating binary triggers.

• The National Firearms Act (NFA) and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) rules define machine guns.

• Binary triggers that fire one round on pull and one on release are not classified as machine guns by the ATF.

• Federal law prohibits possession of machine guns manufactured after 1986 without special licenses.

• Binary triggers are legal federally if they do not enable automatic fire beyond one round per trigger function.

Therefore, federal law permits binary triggers as long as they comply with ATF interpretations.

Which Law Applies in Common Real-World Scenarios?

Understanding which law applies helps avoid legal issues.

• Owning a binary trigger at home: Tennessee law applies; federal law must be followed.

Both federal and state laws must be considered in these scenarios.
