Drop a force reset pack or binary trigger and already have the third position markings on the receiver.

The Fostech model TECH-15 is a semi-automatic AR-15 lower receiver chambered for multi. Constructed from aluminum, this stripped lower serves as the foundational component for AR-15 rifle builds. The receiver is designed to accept standard mil-spec parts and upper assemblies, providing a base for custom configurations or replacement applications. Its design maintains compatibility with multiple calibers within the AR platform, depending on the upper receiver and barrel used.

This TECH-15 lower is in new condition and has not been assembled or modified. The aluminum construction provides durability and structural rigidity suitable for AR-pattern rifles. As a stripped receiver, it does not include a lower parts kit, trigger assembly, or stock components. The machining and dimensions are configured to meet standard AR-15 specifications, allowing integration with commonly available accessories and parts. The surface finish is black anodized for corrosion resistance and uniform appearance.
