80% Lower Fire/Safe Marked – Raw

This 80% lower fire/safe marked – raw component is a foundational element for custom rifle builds, designed for the builder who demands precision from the ground up. Manufactured by 80% to exacting tolerances, this raw forging provides the structural core for a personalized platform. The fire/safe markings are correctly indexed and deeply engraved, ensuring clarity after final finishing. Each unit is machined to accept standard lower parts kits, with all critical dimensions held to mil-spec tolerances. The raw surface allows for custom cerakote, anodizing, or polished finishes, enabling complete aesthetic control. For builders seeking a true starting point, this 80% lower fire/safe marked – raw component eliminates guesswork while maintaining maximum design freedom.

Overview

This 80% lower receiver begins as a precision-forged 7075-T6 aluminum billet, then undergoes CNC machining to create the fire/safe marked pocket and selector detent channels. The raw state means no finish has been applied, leaving the material ready for your preferred surface treatment. All trigger pin holes, hammer pin holes, and safety selector holes are pre-drilled to standard dimensions. The magazine well is fully opened and beveled for reliable feeding. This 80% lower fire/safe marked – raw unit includes the critical fire/safe markings that are laser-etched before machining to ensure alignment with the safety selector. Builders will find the pocket dimensions compatible with nearly all standard trigger groups.

Who It’s For

This 80% lower fire/safe marked – raw is intended for experienced builders who require a precise, unfinished component. It suits gunsmiths performing custom cerakote or anodizing work, as the raw surface accepts finishes without prior stripping. Hobbyists who prefer to control every step of the build process will appreciate the clean machining and accurate fire/safe markings. It is also appropriate for those replacing a damaged lower or building a spare receiver for inventory. While the 80% lower fire/safe marked – raw component simplifies the initial machining, final assembly still requires appropriate tools and knowledge of firearm safety systems. This product is not recommended for first-time builders without prior experience in lower receiver assembly.

Shipping & FFL

This 80% lower fire/safe marked – raw component is classified as a non-firearm receiver blank under current ATF guidelines. It does not require transfer through a Federal Firearms License (FFL) dealer when purchased in its current 80% completion state. However, once machining is completed to a functional 100% receiver, the finished product becomes a firearm and must be transferred per federal and state laws. Customers are responsible for verifying local and state regulations regarding 80% lower receivers before ordering. Standard shipping rates apply, with delivery typically within 5-7 business days to all US states where such components are legal. We do not ship to P.O. boxes or military APO/FPO addresses for this item. No FFL is required for this transaction.
