Are Binary Triggers Legal in Colorado?

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 firearm enthusiasts. In Colorado, the legality of binary triggers is nuanced and depends on specific state and federal regulations.

While Colorado law governs firearm accessories, federal law also plays a role, especially regarding devices that may be classified as machine guns. Understanding both legal frameworks is essential for residents and visitors to ensure compliance and avoid penalties.

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

Yes, owning and using binary triggers in Colorado is generally legal for residents and visitors, provided the device does not meet the federal definition of a machine gun.

• Legal ownership means you can possess and install binary triggers on compatible firearms.

• Use is permitted on private property and designated shooting ranges following all safety rules.

• Sales and transfers must comply with state and federal firearm laws.

• Manufacturers and sellers must ensure devices do not violate federal machine gun statutes.

Overall, binary triggers are conditionally legal, with restrictions primarily based on federal classification.

What Does Colorado State Law Say About Binary Triggers?

Colorado does not have specific statutes explicitly banning or regulating binary triggers, but general firearm accessory laws apply.

• Possession and use of binary triggers are allowed unless the device is classified as a machine gun under federal law.

• Colorado law prohibits possession of illegal machine guns, but binary triggers typically do not meet this definition.

• State law requires compliance with background checks and firearm transfer regulations when buying or selling firearms with binary triggers.

• Enforcement focuses on compliance with firearm possession and use laws rather than accessory-specific rules.

Thus, Colorado law defers largely to federal definitions and regulations concerning binary triggers.

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

Yes, federal law significantly impacts the legality of binary triggers, especially the National Firearms Act (NFA) and the Gun Control Act (GCA).

• The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) regulates devices that alter a firearm's firing mechanism.

• If a binary trigger causes a firearm to fire more than one shot per single function of the trigger, it may be classified as a machine gun under the NFA.

• Binary triggers that fire one round on pull and one on release generally avoid the machine gun classification.

• Federal law preempts state law in cases of machine gun classification, making possession illegal without proper registration.

Federal regulations are the primary legal framework governing binary trigger legality nationwide, including Colorado.
