Franklin Armory's Libertas is a purpose-built billet lower designed for builders who want quality construction and thoughtful ergonomics right from the start. Machined from solid 7075-T6 aluminum and finished in Type III hard-coat black anodize, it's built to last and purpose-engineered to make your AR-15 build feel dialed in.
Solid billet machining means thicker walls throughout the receiver and superior structural integrity compared to forged lowers. This translates to tighter tolerances, less play between upper and lower, and a more refined feel when everything is assembled. The Libertas comes with a specialized tension screw that works to eliminate any remaining movement between your upper and lower receivers, giving you confidence in your build's stability.
The design includes ambidextrous Quick Detach sling mounts that resist rotation and give you secure mounting options. You get an oversized, cold-weather trigger guard that accommodates larger hands or gloved shooting. The flared and beveled magazine well is shaped for faster reloads, and the textured Memory Index Point on the magwell lets your trigger finger find a safe resting position when you're not ready to fire. There's even textured grip area forward of the magazine well for support when using it as a forward grip.
The Libertas ships with a six-position carbine-length buffer tube already installed but no stock included, which means you can choose exactly which stock suits your needs without paying for something you'll swap out anyway. You'll also get a comprehensive safety manual and cable lock.
This lower works for any AR-15 caliber build and accepts standard milspec parts. Whether you're building a 5.56, .308, or something in between, the Libertas gives you a foundation that won't hold you back.
The Libertas is a multi-caliber lower that works with any AR-15 platform caliber, including 5.56 NATO, .308 Winchester, 6.5 Creedmoor, and many others. The lower receiver itself is caliber-agnostic, so compatibility depends on what upper receiver and barrel you pair with it.
No, the Libertas comes with a carbine-length buffer tube installed but no stock. This lets you select your own stock without paying for one you'll likely replace anyway. Just add your preferred stock and you're ready to go.
Billet machining cuts the receiver from a solid block of aluminum, creating thicker walls and tighter tolerances throughout. This results in a more robust construction, better upper-to-lower fit, and a more refined feel compared to forged receivers.
Yes, the Libertas accepts standard milspec AR-15 parts. It's built to work seamlessly with most aftermarket components, making it easy to customize your build exactly how you want it.
The textured Memory Index Point on the magwell provides a safe, intuitive spot for your trigger finger to rest when you're not actively firing. It helps with consistent finger placement and adds another layer of user-friendly design.
The specialized tension screw reduces play between your upper and lower receivers, tightening the fit and improving stability. This keeps everything solid and locked together, which translates to better accuracy and a more refined shooting experience.
