Franklin Armory FAI-15 Multi-Caliber Stripped AR-15 Lower Receiver

The Franklin Armory FAI-15 Stripped Lower Receiver provides a forged foundation for compatible AR-15 configurations. Manufactured from 7075-T6 aluminum, the receiver features a durable black hardcoat anodized finish and is marked Multi for caliber.

The FAI-15 also incorporates Franklin Armory's specialized tension screw, designed to help minimize movement between compatible upper and lower receivers. This listing is for the stripped lower receiver; review the specifications and included components before ordering.

Important clarification: Although distributor data references the BFSIII Series and “Elite Binary Trigger Equipped,” this item is identified as the FAI-15 Stripped Lower. A stripped lower does not ordinarily include an installed trigger assembly. Unless your physical inventory actually includes a Franklin Armory binary trigger, I would not advertise this product as binary-trigger equipped based solely on that conflicting distributor field.

FAQ

What does “Multi” mean on the Franklin Armory FAI-15 lower receiver?

“Multi” is the caliber marking on the receiver rather than a designation for one specific cartridge. Compatibility with a particular AR-15 configuration depends on the other components used with the receiver.
