About the Fostech Tech-15 Complete AR-15

The Fostech Tech-15 lower receiver is a forged aluminum unit, providing a durable foundation for an AR-15 build. It comes pre-assembled with the Fostech Echo Sport trigger, a drop-in binary firing system that allows for a round to be fired on the pull of the trigger and another on the release.

This complete lower receiver is suitable for building a custom AR-15 rifle or pistol. The included Echo Sport trigger offers a distinct firing experience for recreational shooting at the range or for competitive applications where rapid fire is desired.
