Fostech Tech15 Stryker 5.56 16″ with ECHO II Binary Trigger

Three-Position Selector

Safe: Firearm will not fire.

Semi-Automatic: Standard semi-auto operation; fires one round per trigger pull.

Echo Mode: Fires one round when the trigger is pulled and a second round when the trigger is released, significantly increasing effective rate of fire.

Cancel Release Feature: In Echo mode, if you pull the trigger and hold it back, you can move the selector lever back to “Semi” or “Safe” to safely discharge or cancel the release shot without firing the second round.
