Fostech Echo Trigger Kit Ar-15 (1 Trigger)

The Echo Trigger is for the direct impingement AR-15. The Echo trigger comes with a stripped carrier with gas key. The stripped carrier is very similar to a full auto carrier except for a chamfer on the rear of the carrier. The Echo carrier must be used in order for the Echo to function correctly. The customer can modify their existing bolt to match the chamber but FosTecH cannot recommend this practice. The Echo Trigger is a ground breaking drop in design that is approved by the ATF. 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
