The Echo AR-II Trigger is a ground breaking drop in design that is approved by the ATF. The Echo AR-II trigger does not come with a bolt carrier. You will need a full auto bolt carrier in your firearm for the Echo AR-II to function.





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.
