The Fostech Echo II AR Trigger is a revolutionary fast fire trigger system with a groundbreaking drop-in design. It is not select fire, but like firearms with select-fire capabilities, the mode of fire is determined by the position of the safety selector. The 3 position safety switch on the Echo II trigger allows the shooter to choose between Safe, Semi-Auto, and Echo (fire on pull and release) firing options. The Echo mode option provides a greatly reduced gap time between rounds resulting in tighter follow-up shot placement. It is also a ton of fun.

The Echo-II Trigger allows the shooter to select from 3 different settings:

  • Safe Mode: Will not fire.
  • Semi-Automatic Mode: Fires when the trigger is pulled.
  • Echo Mode: Fires when the trigger is pulled and also when the trigger is released.

The Echo II Trigger is designed to work with direct impingement AR-15 rifles and pistols. This is the Gen II variation which is the latest and most advanced version of the Fostech Echo triggers. The original Echo required a separate bolt carrier to function but this Gen II trigger will work in any direct impingement AR-15 rifle utilizing a full auto bolt carrier which virtually all AR’s are currently being produced with. It provides a clean, crisp trigger pull regardless of the firing mode selected and the trigger pull in semi-auto mode is as good as, if not better, than most other standard mil-spec triggers. The Echo II trigger is fully approved by the ATF.

The Echo Trigger is designed with safety being the utmost priority. Even in the Echo Mode if the shooter depresses the trigger firing one round, and decides not to fire the second, the shooter can move the selector to the semi-auto position and a second-round will not fire upon release. In addition, the Echo II trigger has several distinct features making it unique to the marketplace and its drop-in design makes it highly sought after by both recreational and professional shooters. The Echo II is packed full of cutting-edge technology and fires reliably in both the Semi-Auto and Echo Mode options.

Important Note: All Fostech Echo triggers incorporate a patented trigger lock mechanism which prevents the trigger from being pulled unless the round to be fired is seated properly in the chamber. This is important in that it keeps the shooter from potentially outrunning the trigger, thereby preventing potential jams or misfires due to firing out of battery.  This patented feature is unique to Fostech and sets their triggers apart in terms of function and reliability.

The Echo II trigger provides for ultra-reliable function in both the standard Semi-Auto position and the Echo Mode, and they have been the subject of numerous videos and reviews. These things are awesome.
