Fostech Echo Sport

Shoot Your AR on Pull and Release

The Fostech Echo Sport is an easy customization that maintains your gun’s semi-automatic status, firing one round per trigger action. Instead of a standard trigger, however, a round is fired when you pull the trigger and again when you release the trigger.

• Replaces the standard trigger group on almost any MILSPEC-style AR-15 receiver.
• A full-auto type bolt carrier group (BCG) is required. This does not affect your weapon’s semi-automatic action as long as a semi-automatic trigger, like the Echo trigger, is used.
• Echo is selectable with a trigger-mounted paddle, maintaining your current safety’s function.
• Cannot be shipped to CA, CT, DC, FL, HI, IA, MD, NJ, NY, RI, and WA.
