FRNKLN 00-20003-BLK LIBERTAS STRIP BILLET LOWER

The Franklin Armory LIBERTAS STRIP BILLET LOWER in black (MPN 0020003BLK) is a precision-machined aluminum lower receiver designed for modern rifle platform assembly and customization. As a billet-forged component, this lower provides shooters with a solid foundation for building or completing an AR-platform rifle with exacting tolerances and superior structural integrity compared to traditional forged alternatives.

The billet manufacturing process removes material from a solid aluminum block rather than using impact forging, resulting in a denser grain structure and tighter dimensional consistency. This approach eliminates the internal stress points common to forged lowers, translating to more predictable metal properties during machining and assembly. Operators working on precision builds value this level of control when fitting trigger groups, buffer tube assemblies, and fire control components. The black anodized finish provides corrosion resistance suitable for field storage and varied weather exposure, though proper maintenance remains essential for long-term durability.

Billet lowers appeal to builders seeking maximum customization flexibility and those prioritizing aesthetic presentation of the finished rifle. The LIBERTAS STRIP configuration allows complete freedom in selecting trigger assemblies, pistol grips, stock systems, and safety selectors without factory constraints. This component is ideal for range enthusiasts, competitive shooters, and operators assembling platform-specific rifles tailored to particular shooting disciplines or mission requirements.

At 0.62 lbs and measuring 4.5 × 1.2 × 7.7 inches, the lower receiver integrates seamlessly into standard AR-platform builds. Ensure compatibility with your chosen upper receiver assembly, fire control group, and buffer tube system before purchase. This component is subject to all applicable federal firearms regulations and local laws governing receiver ownership and transfer.
