Fostech – ECHO Sport Trigger for AR-15 Platform

As with all binary triggers, you will need to run a full-auto bolt carrier group (BCG) in order for your AR15 to run properly.

The Echo Trigger has three positions:

  • Safe Mode – The firearm will not fire.
  • Semi-Auto Mode – Like standard triggers, the firearm fires will the trigger is pulled.
  • Echo Mode – The firearm fires when the trigger is pulled and when the trigger is released which makes for a rapid rate of fire.

As of March 2022, the Bureau of Alcohol, Tobacco, and Firearms issued their opinion on binary triggers allowing for their legality as they do not make firearms fully automatic.

We cannot ship binary triggers to the following states because they have been banned per State Law: California, Colorado, Connecticut, Delaware, Florida, Hawaii, Idaho, Illinois, Iowa, Maryland, New Jersey, New York, Rhode Island, Virginia, and Washington.
