The Echo AR II Trigger from FosTech Outdoors is an ATF-approved rifle trigger built specifically for AR 15 platform weapons. These Rifle Triggers feature an innovative drop-in design for easy installation, and deliver crisp, light pulls while in semi-auto mode. Overall, the Fostech Echo Trigger has 3 different modes: safe (firearm will not fire), semi-auto (gun fires when trigger is pulled), and echo (weapon fires when trigger is pulled and released). These drop-in AR 15 triggers require a full-auto bolt carrier to function properly, and bolt carriers are not included with purchase.

With drop-in installation, cutting-edge technology, and clean trigger pulls, the Echo AR-II Trigger is an excellent addition to your AR platform. Grab one of these AR 15 triggers from Fostech today to improve your shooting technique and deliver top-level performance, shot after shot.
