Whether you are starting a new build or replacing a damaged lower, this 80% lower fire/safe marked – anodized black unit delivers reliable geometry and clean aesthetics.

Features & Specs

This 80% lower is machined from 7075-T6 aluminum and finished with a Type III hard coat anodized black surface. The fire/safe markings are positioned on the left side of the receiver for easy reference with standard selector switches. All critical pin holes and trigger pocket dimensions are pre-machined to within 0.001 inch of mil-spec tolerances, leaving only the fire control pocket, hammer and trigger pin holes, and selector detent channel requiring final machining. The anodized black finish is non-reflective and resists scratches, solvents, and wear during the building process.

• Material: 7075-T6 aluminum with Type III hard coat anodized black finish
• Selector markings: Laser-etched fire (semi-auto) and safe positions, clearly visible on left side
• Pre-machined features: Trigger pocket floor, hammer and trigger pin holes, and selector detent channel require final machining by the builder

Who It’s For

This 80% lower fire/safe marked – anodized black component is intended for experienced hobbyists, gunsmiths, and builders who have the tools and knowledge to complete the final machining steps.

The anodized black finish and clear fire/safe markings make it suitable for both functional builds and display projects.
