These Binary 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).
