The FosTech Echo Sport trigger (FosTech part number 4140) is an economical pull-and-release trigger for the AR-15 platform, built with the same core functionality as FosTech’s ECHO AR-II. Instead of switching modes from the safety selector, the Echo Sport uses a two-position paddle above the trigger, called the Echo Selector, to move between standard semi-automatic and echo mode, and that same paddle lets shooters negate the second round when needed. It is not a drop-in trigger and does not include an ambidextrous safety, but it delivers the ECHO functionality at a more affordable price point.
