Bullet Button Assault Weapon

Do I need to register my bullet button firearm?

Assembly Bill 1135 and Senate Bill 880 require that any person who, from January 1, 2001, to December 31, 2016, inclusive, lawfully possessed an assault weapon that does not have a fixed magazine, as defined in Penal Code section 30515, including those weapons with an ammunition feeding device that can be readily removed from the firearm with the use of a tool (commonly referred to as a bullet-button) must register the firearm before January 1, 2018. However, Assembly Bill 103 has since extended the registration period from January 1, 2018 to July 1, 2018.

Assembly Bill 1135 and Senate Bill 880 also define the meaning of "fixed magazine" to mean an ammunition feeding device contained in, or permanently attached to, a firearm in such a manner that the device cannot be removed without disassembly of the firearm action.

This legislation closes the "bullet button" loop hole and categorizes "bullet button" firearms as assault weapons. The adopted regulations for bullet button assault weapon registration contains additional information on registration requirements.
