About this product

80% Lower Fire/Safe Marked – Raw

This 80% lower fire/safe marked – raw component is a precision-machined, unfinished receiver forging designed for the builder who demands control over every step of the manufacturing process. Constructed from 7075-T6 aluminum billet and left in a raw, uncoated state, this part serves as the foundational platform for a custom AR-pattern build. The fire/safe markings are laser-etched prior to shipment, providing clear, permanent selector indicators without additional finishing steps. As an 80% component, this item requires further machining, drilling, and finishing to become a functional firearm receiver, and it is not classified as a firearm by the ATF.

Overview

The 80% lower fire/safe marked – raw is intended for the experienced hobbyist, gunsmith, or manufacturer who wishes to complete a lower receiver from an unfinished state. The raw surface finish allows for custom anodizing, cerakoting, or other coatings, while the pre-marked fire/safe engravings eliminate the need for post-machining laser work. This product is machined to mil-spec dimensions, ensuring compatibility with standard AR-15 upper receivers, trigger groups, and buffer tube assemblies. All critical pin holes are left undrilled, allowing the builder to achieve exact tolerances during the finishing process.

Features & Specs

Manufactured by 80% and categorized as a firearm part, this raw lower is produced from a solid billet of 7075-T6 aluminum, heat-treated to T6 temper for maximum strength and corrosion resistance. The fire/safe markings are engraved at 0.015-inch depth, visible through any applied coating. The pocket and trigger area are rough-machined to within 0.010 inches of final dimensions, reducing material removal time during completion. Specific features include:

• Material: 7075-T6 aluminum billet, MIL-A-8625F specification, raw unfinished surface for custom finishing
• Markings: Laser-etched “FIRE” and “SAFE” indicators on selector side, positioned to mil-spec angular orientation
• Machining: 80% completion state with undrilled trigger pin, hammer pin, and safety selector holes; pocket and shelf rough-machined
• Compatibility: AR-15 pattern, DPMS-style, compatible with all standard mil-spec lower parts kits and buffer tubes
• Weight: 10.2 ounces raw; will vary slightly after finishing and component installation

Additional technical details for the 80% lower fire/safe marked – raw include a shelf height of 0.625 inches for standard AR-15 fire control groups, a buffer tube thread pattern of 1.250-18 UNEF, and a trigger guard that is integrally machined. The raw surface allows for direct application of Type III hard coat anodizing, phosphate, or polymer finishes without pre-treatment beyond degreasing.

Who It’s For

This 80% lower fire/safe marked – raw is intended for individuals who possess the tooling and expertise to complete an unfinished receiver. Typical users include:

• Home gunsmiths with access to a drill press, jig, and end mills who require a pre-marked lower for accurate selector engagement
• Small-scale firearm manufacturers who batch-complete multiple lowers and prefer raw aluminum for uniform coating application
• Competition shooters and custom builders who need a clean, uncoated base for specialized finishes such as cerakote or nitride
• Hobbyists who want to avoid the cost and lead time of post-machining laser engraving for fire/safe markings

The raw state of this component allows the builder to achieve exact trigger pull weights and selector throw angles through hand-fitting, which is not possible with fully finished production receivers.
