The Franklin Armory Libertas represents a thoughtful approach to modern rifle design, combining precision engineering with practical features that serve both the experienced shooter and those new to the platform.

Construction & Materials

Machined from 7075-T6 aluminum and finished with hard-coat Type III anodizing, this billet lower receiver offers durability without unnecessary weight. The proprietary design incorporates a specialized tension screw system that effectively eliminates upper and lower receiver play—a detail that matters when accuracy is the goal.

Ambidextrous Design: Push-button QD sling mounts on both sides accommodate shooters of any preference. The integral cold-weather trigger guard allows operation with gloved hands, a practical consideration for field use.

Grip & Control: The textured front area provides positive purchase for offhand shooting, while the serrated memory index point on the trigger guard helps maintain consistent finger placement. The included Ergo Ambi Sure Grip offers comfortable, secure control.

Magazine Handling: The flared magazine well facilitates quick, intuitive magazine changes under any conditions.

Binary Firing System

The integrated Franklin Armory Binary Firing System fires on both trigger press and release, effectively doubling your rate of fire within legal parameters. This system is factory-installed and ready to use.

Included Components

Ships complete with Magpul P30 magazine, B5 SOPMOD stock, and six-position receiver extension. All components are Mil-Spec diameter compatible.

The Bottom Line

This is a lower receiver built for shooters who understand that details matter. Whether you're building a precision rifle or a practical defensive platform, the Libertas delivers thoughtful engineering and reliable performance.
