Franklin Armory FAI-15 Stripped Lower Black 5.56 / .223 Rem Binary Marked

DESCRIPTION 
The Franklin Armory FAI-15 stripped lower is built on a forged 7075-T6 aluminum foundation, delivering a rigid, lightweight, and durable base for performance-driven AR builds. Its hardcoat anodized finish provides long-term surface protection while maintaining a clean, professional appearance. Binary markings are correctly applied for builders configuring BFSIII-style systems, ensuring proper visual alignment with the platform.

A specialized tension screw allows users to fine-tune receiver fitment, reducing upper-to-lower movement for a tighter, more consistent interface. The Elite Binary Trigger Equipped configuration supports a complete BFSIII setup without requiring additional receiver modifications. For builders seeking a premium, properly configured starting point, the FAI-15 offers a purpose-built forged lower ready for advanced performance applications.
