The FosTech Echo Sport is the lower-cost paddle selector trigger in FosTech Outdoors‘s Echo line, built for AR-15 platform rifles (FosTech part number 4140). Rather than a dual selector, it uses a single paddle located inside the trigger guard to switch between standard and enhanced fire modes. It still gives the three settings of the Echo family: Safe, Semi-Automatic and Echo. In Echo Mode the firearm fires when the trigger is pulled and also when it is released. FosTech states you will need a full-auto bolt carrier for it to function, and the trigger does not come with one.
