80% Lower Fire/Safe Marked – Raw

Overview

This 80% lower fire/safe marked – raw component is manufactured by 80% to serve as an unpainted, unengraved foundation for custom AR-15 builds. Designed as a Parts category item, this lower receiver blank is machined from billet aluminum and features standard fire/safe selector markings. The raw finish allows for custom cerakote, anodizing, or other surface treatments at the builder’s discretion. Critical dimensions are held to mil-spec tolerances, ensuring compatibility with standard upper receivers, lower parts kits, and buffer tube assemblies. This 80% lower fire/safe marked – raw unit requires final machining of the fire control pocket, trigger pin holes, and safety selector channels before it can function as a serialized receiver. All material excess is removed at the factory except for the key areas left intact to comply with ATF regulations for non-firearm blanks.

Features & Specs

Every 80% lower fire/safe marked – raw blank is machined from 7075-T6 aluminum billet and includes the fire and safe selector position engravings as standard. The raw state means no coating, no anodizing, and no finish is applied, giving the builder full control over the final appearance. The fire control cavity is pre-machined to 80% completion, leaving the trigger slot, hammer pin holes, and safety detent recesses as unfinished surfaces. All external dimensions match mil-spec AR-15 lower receiver geometry, including the buffer tube threads, trigger guard hole placement, and takedown pin lug locations. The fire/safe markings are laser-engraved on the left side of the receiver, consistent with standard selective-fire nomenclature for semi-automatic builds. This 80% lower fire/safe marked – raw part is compatible with all standard AR-15 jigs and drill guides designed for 80% receiver completion.

• Material: 7075-T6 aluminum billet with raw, unfinished surface
• Machining: 80% completed fire control pocket, trigger and hammer pin holes left solid
• Markings: Laser-engraved “FIRE” and “SAFE” selector positions on left side
• Weight: Approximately 0.9 pounds in raw state before finishing

Who It’s For

This 80% lower fire/safe marked – raw is intended for experienced hobbyists, gunsmiths, and manufacturers who possess the tooling and skill to complete the remaining 20% of the machining process. The raw finish suits builders who plan to apply custom coatings, including cerakote, duracoat, or hard anodizing, and who require a blank without any pre-applied finish that might interfere with adhesion. This component is also appropriate for small-scale custom shops producing serialized receivers for clients, provided all federal, state, and local regulations are followed regarding receiver completion and serialization. Because the fire/safe markings are already present, builders can avoid the need for post-machining engraving of selector positions. This 80% lower fire/safe marked – raw is not suitable for first-time builders without proper jigs, drill presses, or router setups.

• Ideal for custom cerakote or hydrographic finish applications
• Designed for builders using commercial AR-15 completion jigs
• Not for users lacking machining experience or appropriate tools
