Understanding the Echo Trigger System
What is a Binary Trigger?
A binary trigger, such as the Echo AR II and Fostech Echo II, is a revolutionary firearm component that fires one round when the trigger is pulled and another when released in its Echo Mode. This “double-tap” effect creates a feedback loop, delivering instantaneous response and significantly increasing firing speed. Unlike fully automatic systems, binary triggers remain semi-automatic, requiring deliberate trigger actions for each shot, ensuring compliance with federal regulations. This makes them a popular choice for shooters seeking near-automatic performance without the legal complexities of NFA items.
The Echo AR II and Fostech Echo II triggers are engineered for precision and durability, integrating seamlessly with AR-15 platforms. Their patented designs (e.g., US Patent #8,820,211 B1) reflect years of innovation, offering shooters a reliable and versatile upgrade. These triggers are particularly appealing for their ability to enhance tactical scenarios, competitive shooting, and recreational range sessions, making them a cornerstone of modern firearm technology.
