The Echo AK-47 Trigger by FosTecH is a highly advanced drop-in trigger that provides a binary firing option for AK-47 platform rifles and pistols. The AK-47 Echo is designed as a dual function trigger that, when set to Echo mode, allows the shooter to fire a round on both the pull and the release of the trigger. The 3-position selector plate installs as part of the Echo trigger system and lets the shooter choose between Safe, Semi-Auto, and Echo firing options. The Echo mode option provides a greatly reduced gap time between rounds, resulting in tighter follow-up shot placement. The AK-47 version has been approved by the ATF and is ready for AK platform firearms. It is designed to work with stamped AKs, and milled AKs should also work as long as you are willing to work with the mode selector plate and the trigger blade in some cases. Current platforms tested include various stamped AKs and milled variants. All sales terms and restrictions apply as listed by the retailer.
