Why Choose This 80% Lower Receiver?
An 80% lower receiver represents the ideal starting point for firearm enthusiasts who want to build their AR-15 from the ground up. Unlike completed receivers, this 80% version requires final machining to become functional, allowing you to complete the manufacturing process yourself. This approach offers several advantages:

- Enhanced Privacy: Since you complete the manufacturing, you maintain greater control over your firearm’s documentation
- Educational Experience: Gain valuable gunsmithing skills and deeper understanding of AR-15 mechanics
- Cost-Effective Solution: Building your own firearm can be more economical than purchasing a complete rifle
Premium Forged Construction
The MAS Defense lower receiver begins as a solid block of 7075-T6 aluminum, one of the strongest aluminum alloys available for firearm applications. Through precision forging, the material gains enhanced grain structure and superior strength characteristics compared to cast alternatives. This forging process ensures:
- Exceptional resistance to stress and impact
- Consistent wall thickness throughout the receiver
- Superior dimensional stability under varying conditions
- Long-lasting durability that withstands rigorous use
Raw Finish with MAS Logo
This lower receiver comes in a raw, unfinished state, allowing you complete control over the final appearance. The bare aluminum surface provides the perfect canvas for your preferred finishing method, whether you choose anodizing, cerakote, or other custom coatings. The distinctive MAS logo is prominently displayed, representing the quality and craftsmanship behind this component.
Compatibility and Specifications
Designed to Mil-Spec standards, this lower receiver ensures compatibility with a wide range of AR-15 parts and accessories. The precise machining maintains tight tolerances for reliable operation with various upper receivers and internal components.
