Have you been wanting an echo trigger but have been turned off by the silver color? We have you taken care of! Meet the Black Echo. The Black Echo is identical to the factory echo trigger, but we have Cerakoted the trigger in H-Series Armor Black. This trigger is not available anywhere else like this and you will not be able to find anything comparable.

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

  • Safe Mode: Firearm will not fire.
  • Semi-Automatic Mode: Firearm fires when trigger is pulled.
  • Echo Mode: Firearm fires when trigger is pulled and also when trigger is released.

The Echo Trigger is designed with safety being the utmost priority. When the shooter is in the Echo Mode and depresses the trigger one round is fired, if the target moves, the shooter can move the selector to the safe position and a second round will not fire upon release.

The echo trigger has several distinct features

  • PATENTED Design that gained ATF Approval (Patent # US 8,820,211 B1)
  • Technology licensed through HIPERFIRE inside the Echo Trigger
  • Light, clean, and crisp pull in Semi-Automatic Mode
  • The Echo Trigger is packed full of cutting edge technology
  • Reliable function in Echo Mode

*Please note that Fostech will most likely NOT warranty this trigger as it has been Cerakoted outside of their facilities. *

 We cannot ship Echo triggers to CA, DC, IA, NJ, NY, HI, RI, FL, MD, CT, DE, MA, or WA

    Well worth it to have the trigger cerakote and selector switch upgrade. I also received the 3-gun and tactical spring upgrade for free along with a $75 store credit. I don’t know how long trigger depot plans on offering the $75 gift card with all echo purchases, but I’d get on that while it lasts. Either way, it’s worth it to buy the echo trigger here at trigger depot.
