Franklin Armory FAI-15 Multi-Cal Forged AR-15 Stripped Lower - Binary Marked - Black

The Franklin Armory FAI-15 is a stripped lower receiver for the AR-15 platform, forged from 7075-T6 aluminum and finished in a hard coat Type III anodized black. This lower is Binary marked on the receiver to designate compatibility with Franklin Armory's BFSIII binary trigger system, and ships with the specialized tension screw required for that installation.

Designed as a multi-caliber foundation for custom AR-15 builds, the FAI-15 accepts standard .223 Remington and 5.56 NATO uppers and uses the standard AR-15 lower parts kit for completion. As a stripped lower, this is the serialized foundation piece only - it does not include a lower parts kit, pistol grip, buttstock, trigger, or any upper components, and must be completed by the end user before it can function as a firearm.

• Hard coat Type III anodized black finish
• Multi-caliber markings for .223 Remington and 5.56 NATO
