Binary trigger
A BinaryⓇ trigger (or pull and release trigger) is a device that allows a semi-automatic firearm to fire one round when the trigger is pulled and one when it is released. The term "Binary" is a trademark of Franklin ArmoryⓇ.[1]
While BinaryⓇ triggers are available in factory firearms, they are often used to replace the original fire-control group. As in all semi-automatic firearms, only one round is fired within a single function of the trigger. This allows guns outfitted with a BinaryⓇ trigger to avoid classification as a machine gun within the definitions used by United States federal law and most state laws, as stated by various ATF private-letter rulings.[2][3]
However, as with all private-letter rulings, these determinations on the U.S. legality of BinaryⓇ triggers are limited to the specific facts about the devices being examined. Any such legal opinion may be modified or revoked at any subsequent time by the United States Congress. Furthermore, agency opinion is not always considered correct or legally binding. See Garland v. Cargill.
BinaryⓇ triggers became popular in the United States beginning in 2015.[4] However, in wake of the 2017 Las Vegas shooting, BinaryⓇ triggers also received scrutiny by progressive media outlets.[5] The Minnesota State Legislature began debating a ban on BinaryⓇ triggers following their use in the 2024 Burnsville shooting.[6]
