Binary Trigger for AR15

A binary trigger for AR15 rifles has become a popular upgrade among firearm enthusiasts looking to enhance trigger responsiveness while remaining within legal semi-automatic classifications in many jurisdictions. This guide explains what a binary trigger is, how it works, its benefits and drawbacks, legal considerations, and what to look for before purchasing.

What Is a Binary Trigger for AR15?

A binary trigger is a specialized trigger system that fires one round when the trigger is pulled and a second round when the trigger is released. Unlike traditional AR15 triggers, which fire only on the pull, a binary trigger allows two distinct firing actions within one full trigger cycle.

Importantly, a binary trigger does not convert an AR15 into a fully automatic firearm. Each shot still requires a separate mechanical action by the shooter, which is why binary triggers are often classified as semi-automatic components under U.S. federal law.

Benefits of a Binary Trigger for AR-15

A binary trigger for an AR-15 is a popular firearm upgrade that offers enhanced shooting performance, faster follow-up shots, and improved trigger control. Unlike standard triggers that fire only on the pull, a binary trigger fires one round on the pull and one on the release, providing a unique and controlled shooting experience.
