The Echo ARII Trigger is a trigger for many but not all AR15 platforms. The Echo ARII trigger NO LONGER comes with a stripped carrier with gas key becuase it is no longer needed. You will use the M16 bolt carrier group alread inside your weapon. If you do not have a full auto carrier group in your weapon you will need to obtain a full auto carrier in order for the Echo ARII trigger to function. The Echo ARII Trigger allows the shooter to select from 3 different settings: Safe Mode: Firearm will not fire. Semi-Automatic Model: Firearm fires when trigger is pulled.
