FosTecH Echo AR-II Trigger – High-Speed AR Upgrade

The Echo AR-II Trigger from FosTecH delivers fast, smooth follow-up shots and enhanced control for your AR-15. Featuring a patented dual-selector design, it allows quick transitions between Safe, Semi, and enhanced fire modes. Built for tactical reliability and easy installation, this AR-15 trigger upgrade is perfect for tactical training, or range use. Proudly made in the USA and fully ATF-approved.

The Echo Trigger allows the shooter to select from 3 different settings:

• Safe Mode: Firearm will not fire.
• Semi-Automatic Mode: Firearm fires when the trigger is pulled.
• Echo Mode: Firearm fires when the trigger is pulled and also when the trigger is released.

The Echo AR-II Trigger isn’t just a trigger—it’s a testament to precision, control, and pure FosTecH ingenuity.
