80% Lower Fire/Safe Marked – Anodized Black

Overview

Building your own AR-15 platform from an 80% lower gives you control over every component, but the finishing touches matter. This 80% lower fire/safe marked – anodized black is a clean, pre-marked receiver that takes the guesswork out of your selector engraving. The anodized black finish is consistent and durable, matching standard mil-spec components without the need for cerakote or refinishing. Whether you are a first-time builder or a seasoned gunsmith, this lower provides a solid foundation with the fire/safe markings already laser-etched into the aluminum, saving you a step in the finishing process. The price point reflects a quality part without the premium markup you might see from boutique brands.

Features and Specs

This 80% lower fire/safe marked – anodized black is machined from 7075-T6 aluminum, the same material used in mil-spec forged receivers. The anodized black coating is not just cosmetic; it resists corrosion and wear during handling and drilling. The fire/safe markings are deeply etched and clearly visible against the black finish, ensuring your selector position is unambiguous once the lower is completed. The pocket dimensions are within standard tolerances, making jig alignment straightforward.

Who It Is For

This part is ideal for the home builder who wants a finished look without having to engrave selector markings themselves. If you are assembling a pistol, rifle, or SBR and want the fire/safe markings to match a factory lower, this 80% lower fire/safe marked – anodized black is a practical choice. It suits builders who prefer a pre-marked receiver because it reduces the risk of misaligned engraving after machining. The anodized black finish also blends well with most standard buffer tubes, grips, and handguards, so you do not have to worry about color mismatch. Whether you are building a spare lower for the range or a dedicated precision setup, this part eliminates one more variable from the build.

• Home gunsmiths and first-time 80% builders
