The FosTech Echo AK Drop-In Trigger for the AK-47 platform (brand part no. 4702) is a selectable-mode trigger built primarily for stamped-receiver AKs, giving shooters three settings to choose from at the flip of a selector. Safe Mode blocks the firearm from firing, Semi-Automatic Mode fires once per trigger pull, and Echo Mode fires once on trigger pull and again on trigger release. Because AK-pattern rifles and pistols vary in internal tolerances between manufacturers, FosTech notes that milled-receiver AKs may need minor adjustment to the mode selector plate or trigger blade, though a number of milled models have tested compatible out of the box. This trigger is a drop-in part, not a full lower assembly, so installation stays within the existing trigger group housing.
