Fostech Echo Ar-15 Trigger Safe Semi Echo Modes

The Fostech Echo AR-ll Trigger For AR-15 delivers advanced control and reliability in a precision AR platform, using a patented design that has earned ATF approval and licensed technology from Franklin Armory and HIPERFIRE to provide a clean, crisp pull in Semi-Automatic Mode. This trigger offers three selectable settings—Safe Mode, where the firearm will not fire; Semi-Automatic Mode, where the firearm fires with each trigger pull; and Echo Mode, where the firearm fires on both trigger pull and release, yet remains safety-conscious: if a target moves, you can switch to Safe and prevent a second round from firing upon release. The Echo Trigger is engineered with safety as the utmost priority, delivering reliable function in Echo Mode while maintaining controlled operation in all modes. Patented technology within the Echo AR-II Trigger, along with licensed innovations, ensures a smooth, predictable feel that enhances accuracy and user confidence across a variety of tactical and hunting scenarios. Built to integrate seamlessly with AR-15 platforms, this trigger supports precise shot execution and deliberate, responsible shooting behavior in dynamic environments.
