Blemished – 80% Lower Fire/Safe Marked – Anodized Black

Overview

This blemished – 80% lower fire/safe marked – anodized black component offers a cost-effective entry point for your custom firearm build. Designed for the builder who values function over cosmetics, this lower receiver features a subtle cosmetic blemish from the machining or anodizing process. It is not a factory second in terms of structural integrity; each unit is inspected to ensure it meets standard material and dimensional tolerances. The fire/safe markings are laser-engraved and clearly visible, matching standard AR-15 lower receiver layout. The anodized black finish provides a durable, corrosion-resistant surface. Because this is an 80% lower, it requires finishing the fire control cavity and trigger pocket before it can accept standard lower parts. This part is sold as a non-firearm receiver blank under current ATF guidelines.

Features & Specs

The blemished – 80% lower fire/safe marked – anodized black receiver is machined from 7075-T6 aluminum billet, then hard-coat anodized in black. The blemish is typically a small surface scratch, tool mark, or anodizing irregularity that does not affect function. Fire/safe markings are engraved into the side of the magazine well, positioned for standard selector lever indexing. The pocket dimensions are within MIL-SPEC tolerances for jig compatibility. All necessary datums and locating surfaces are present for jig alignment.

Who It’s For

This blemished – 80% lower fire/safe marked – anodized black receiver is intended for the experienced home builder who wants to save money on a component that will be refinished, cerakoted, or used in a budget build. It is not for collectors or those requiring pristine cosmetic appearance. The blemish is present and will be visible upon close inspection. If you plan to paint or coat the lower, the blemish will be covered. This part is suitable for builders who have access to a drill press, router jig, and end mills to complete the fire control pocket. It is not a complete firearm and requires additional machining. The fire/safe markings are already applied, so you will not need to engrave them after finishing.
