80% Lower Fire/Safe Marked – Raw

Overview

This 80% lower fire/safe marked – raw component is a foundational part for builders who demand precision and clarity in their firearm projects. Manufactured by 80%, this raw lower receiver is machined to the strictest tolerances, providing a clean, uncoated surface ready for your customization. The fire/safe markings are laser-etched to military-spec depth and alignment, ensuring legibility through any finish you apply. Whether you are completing a personal build or supplying your shop, this 80% lower fire/safe marked – raw unit offers the durability and compliance required for a reliable final product.

Each 80% lower fire/safe marked – raw piece is CNC machined from solid billet 7075-T6 aluminum. This specific alloy choice gives you a superior strength-to-weight ratio compared to standard 6061, making it ideal for both range use and duty applications. The raw finish means no anodizing or coating is applied, allowing you to apply cerakote, anodize, or duracoat directly to the bare metal. For builders who want their markings to remain crisp and visible under any treatment, the fire/safe engravings on this 80% lower fire/safe marked – raw component are cut deep enough to survive sandblasting and refinishing.
