The Aero Precision AR15 Stripped Lower is a bare, unassembled lower receiver designed as the foundation for custom AR-15 builds. As a stripped lower, it does not include components such as the trigger, safety selector, buffer tube, or stock, allowing builders to select and install their preferred parts. It is a serialized component and considered the firearm under U.S. law, requiring a background check and transfer through a licensed dealer. Crafted from high-strength 7075-T6 aluminum, the AR15 Stripped Lower is precision-machined to Mil-Spec standards, ensuring compatibility with most AR-15 components and upper receivers. It features a clean, anodized Type III hardcoat finish for durability and corrosion resistance. The stripped lower includes threaded bolt catch pins and an integrated trigger guard for ease of assembly and enhanced durability. With its rugged construction and versatile design, the Aero Precision AR15 Stripped Lower is an excellent starting point for AR-15 builders seeking quality and customization.
