80% Lower Fire/Safe Marked – Raw

Overview

This 80% lower fire/safe marked – raw component is a precision-machined, un-serialized receiver blank designed for builders who require a clean, specification-correct platform. Manufactured from 7075-T6 aluminum billet, this raw 80% lower features clearly engraved fire/safe selector markings that align with mil-spec dimensions. The 80% lower fire/safe marked – raw is intended for advanced hobbyists and qualified gunsmiths who will complete the remaining machining operations to produce a functional lower receiver. The part is sold as a non-firearm component under current ATF classifications and contains no fire control group pocket, no trigger pin holes, and no serial number. All critical reference surfaces are held to +/- 0.005 inch tolerances, ensuring compatibility with standard AR-15 upper receivers and buffer tube assemblies.

Features & Specs

The 80% lower fire/safe marked – raw is machined from a solid block of 7075-T6 aluminum, hard-coat anodized in its raw state for corrosion resistance without added finish weight. The fire/safe markings are laser-engraved at 0.020 inch depth for permanent legibility. This 80% lower fire/safe marked – raw is compatible with all mil-spec AR-15 lower parts kits, pistol grips, and buttstocks. The trigger pocket is left 95% complete, requiring end-user finishing with a standard drill press or CNC jig. The selector detent channel and hammer pin holes are pre-drilled to guide, but not complete, the final machining steps.

• Markings: Laser-engraved “FIRE” and “SAFE” selector positions per mil-spec font and spacing.
• Dimensions: 8.5 inches overall length, 1.2 inches width at magwell, 0.065 inch wall thickness in buffer tower.

• Reinforced front pivot pin boss with 0.250 inch wall thickness for increased durability.

Who It’s For

This 80% lower fire/safe marked – raw is intended for the experienced builder who possesses the tools and knowledge to complete the remaining 20% of machining. It is suitable for DIY gunsmiths, custom rifle assemblers, and individuals who prefer to finish their own receiver to exact personal specifications. The 80% lower fire/safe marked – raw is not for first-time builders; completion requires a drill press or CNC jig, end mills, and a thorough understanding of AR-15 receiver geometry. Compliance with all federal, state, and local laws regarding receiver manufacturing and serialization is the sole responsibility of the purchaser. This product is designed for lawful use in building a personal firearm for non-commercial purposes.
