Designed to function in the AR-15 platform, the Echo AR-II Drop-In Trigger is a ground breaking drop-in design that is approved by the ATF. The drop-in trigger allows the shooter to select from three different settings including Safe Mode, firearm will not fire; Semi-Automatic Mode, firearm fires when trigger is pulled; and 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 Mode and a second round will not fire upon release. The Echo AR-II Drop-In Trigger does not come with a bolt carrier and a full-auto bolt carrier is required in your firearm for the Echo AR-II to function. If you have any questions about whether you have a full auto carrier or not, please visit echoquestions.com.
