80% Lower Fire/Safe Marked – Anodized Black

For builders who demand precision from the first cut, the 80% lower fire/safe marked – anodized black component provides the exact markings and finish required for a professional-grade AR-15 platform. This 80% lower receiver is manufactured to mil-spec dimensions, allowing for a seamless integration with standard lower parts kits and buffer tube assemblies. The anodized black finish offers corrosion resistance and a low-glare surface, while the clearly engraved fire/safe markings ensure compliance with build standards. Whether you are completing a new pistol or rifle configuration, this 80% lower fire/safe marked – anodized black component serves as the foundation for a reliable firearm.

Overview

This 80% lower receiver is machined from 7075-T6 aluminum and finished with a Type III Class 2 hard coat anodize in black. The 80% lower fire/safe marked – anodized black designation indicates that the fire control pocket and trigger pin holes are un-machined, requiring end-user completion with a jig and router or drill press. The selector markings are laser-etched and filled with white paint for high visibility. The part is manufactured by 80% and categorized under Parts, making it suitable for custom builds, replacement frames, or inventory stocking for gunsmiths. No trigger guard is included, allowing the builder to select their preferred trigger guard style.

Features & Specs

  • Material: 7075-T6 aluminum forging with MIL-A-8625 Type III Class 2 hard coat anodized black finish
  • Markings: Laser-etched “FIRE” and “SAFE” selector indicators with white paint fill on both sides of the receiver
  • Compatibility: Standard AR-15 mil-spec lower parts kits, buffer tubes, and pistol grip dimensions

The 80% lower fire/safe marked – anodized black receiver is pre-drilled for the rear takedown pin and bolt catch pin, but the fire control pocket, trigger slot, and hammer pin holes require machining. The receiver extension threads are pre-cut to mil-spec 1-3/16-18 for standard buffer tube installation. Weight is approximately 9.5 ounces prior to machining. The anodized black finish measures 0.002 inch minimum thickness per mil-spec requirements, providing durability against holster wear and handling. All critical dimensions are held to plus or minus 0.005 inch for consistent fitment across brands.

Who It’s For

This component is intended for individuals who possess the tooling and technical knowledge to complete an 80% lower receiver. The 80% lower fire/safe marked – anodized black variant is ideal for hobbyists who prefer a pre-marked receiver to avoid the need for aftermarket engraving services. It is also suited for gunsmiths building custom rifles for clients who require a specific selector marking configuration. Law enforcement armorers and competitive shooters who maintain multiple lower receivers may use this as a cost-effective base for spare builds. Note that this product is not a finished firearm and does not contain a serial number. Buyers should verify their local and state laws regarding 80% lower receiver possession and completion before purchasing.

Shipping & FFL
