Fostech Echo AR II Gen 2 Binary Drop In Trigger For AR-15 Proprietary Bolt Carrier Not Req'd

Earlier versions of this trigger required the use of Fostech's proprietary bolt carrier. The Echo AR II can accept any full auto bolt carrier.

The Fostech Echo AR-II Binary 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 AR-II 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.

Warning: Binary triggers are not for civilian sales in CA, CT, DC, DE, FL, HI, IA, IL, MD, NJ, NY, RI, and WA. Some states may also not allow them for LE or Military Personnel.
