More about the AR-15 Billet 80% Lower Assembly

For the dedicated firearms enthusiast who values the process of creation as much as the final result, the Premium Fire/Safe Marked Billet 80% Lower Assembly represents a foundational component of a custom AR-15 build. Crafted from high-strength aluminum and featuring a durable anodized finish, this billet-milled lower is designed for builders seeking superior fit, enhanced aesthetics, and the satisfaction of a hands-on project. Its primary use is to serve as the core structural component of a custom rifle, upon which you install your chosen parts kit, upper receiver, and stock to create a personalized firearm.

Key Features

• Billet-Milled Aluminum Construction: Machined from a solid block of 7075-T6 aluminum, this lower receiver offers exceptional strength and rigidity compared to forged counterparts, resulting in tighter tolerances and a more precise fit with your upper receiver.
• Threaded Pin Holes for Simplified Assembly: A significant enhancement includes threaded holes for both the bolt catch release pin and the rear takedown pin detent. This design allows for screw-in installation, eliminating the frustration of launching spring-loaded detents and making the build process more accessible.
• FIRE/SAFE Selector Markings: Cleanly engraved selector markings provide a professional, finished look and offer clear, tactile and visual indicators for the firearm's status.
• Durable Anodized Finish: The hardcoat anodized surface provides excellent corrosion resistance and a wear-resistant foundation for further finishing or cerakoting, ensuring long-term durability.
• Complete Assembly Package: This kit includes not just the 80% lower, but also a lower parts kit, butt stock, and buffer tube assembly. This consolidation provides a logical starting point, ensuring compatibility and reducing the need to source multiple components separately.
• Billet Aesthetic & Enhanced Design: The billet machining process allows for more sculpted lines and flared areas, such as around the magazine well, offering both an aggressive visual profile and improved ergonomics during handling.
