Forged Fire/Safe Marked 80% Lower Assembly

This forged fire/safe marked 80% lower assembly represents a foundational component for builders seeking a precise, unserialized receiver platform. Manufactured to mil-spec dimensions from 7075-T6 aluminum, this lower assembly is designed for those who require a durable, corrosion-resistant base for a custom AR-15 build. The fire/safe markings are laser-etched for permanence and clarity, ensuring compliance with standard lower receiver visual indicators. As an 80% component, it requires final machining to complete the fire control cavity, allowing the builder to maintain control over the final assembly process.

Overview

The forged fire/safe marked 80% lower assembly is a precision-forged component sourced from high-grade aluminum stock. Forging aligns the metal grain structure, providing superior strength compared to billet alternatives. This lower assembly is offered as an uncompleted receiver, requiring the end user to perform the necessary material removal to finish the trigger pocket and safety selector detent channels. The integrated fire/safe markings are applied after forging and prior to anodizing, ensuring the legends remain legible through the hardcoat finish. This product is intended for personal fabrication and assembly, adhering to ATF guidelines for non-licensed individuals.

Who It’s For

This forged fire/safe marked 80% lower assembly is engineered for the experienced hobbyist, gunsmith, and custom builder who values hands-on fabrication. It is appropriate for individuals who possess the required tooling—such as a router, drill press, or jig system—to complete the lower receiver to a functional state. This product suits those building a personalized rifle for recreational shooting, competition, or home defense, where control over component selection is a priority. It is also suitable for purchasers in jurisdictions where 80% receivers are legal to possess and complete for personal use. This assembly is not intended for first-time builders without prior machining experience or proper safety equipment.
