80% Lower Fire/Safe Marked – Anodized Black

The 80% lower fire/safe marked – anodized black is a precision-machined component designed for builders who demand clean markings and a durable finish. This 80% lower receiver blank is fire/safe marked with standard selector engravings, providing a professional look for your custom AR-15 platform build. Constructed from 7075-T6 aluminum and finished in a hardcoat anodized black, this part is ready for you to complete the remaining machining steps at your own pace. As a non-firearm component, it can be shipped directly to your door without FFL transfer for the blank itself, though final assembly and serialization requirements apply per federal law.

Overview

The 80% lower fire/safe marked – anodized black bridges the gap between raw material and a functional lower receiver. It arrives as an unfinished blank with the fire/safe markings already laser-etched, eliminating the need for engraving while still requiring you to complete the trigger pocket, fire control group holes, and buffer tube threads. The anodized black finish is uniform and consistent, matching standard mil-spec components. This lower is manufactured by 80% and categorized under firearm parts, making it a straightforward addition to your build kit.

Who It’s For

The 80% lower fire/safe marked – anodized black is intended for individuals with access to a drill press, jig, and appropriate machining tools who are legally permitted to manufacture a firearm for personal use. It is suited for builders who want the convenience of pre-applied fire/safe markings without paying for custom engraving. This product is not for those seeking a completed, serialized lower receiver. It is designed for personal fabrication only and must comply with all applicable federal, state, and local laws regarding homemade firearms.

Shipping & FFL

Because this item is an 80% lower receiver blank, it is not classified as a firearm by the ATF when sold in its unfinished state. It can be shipped directly to your residence or business without requiring an FFL transfer for the blank. However, once you complete the machining to create a functional lower receiver, you are required to serialize it per ATF guidelines if you intend to sell or transfer it. For personal use, serialization is not federally required but is recommended for documentation. Some states and localities impose additional restrictions on 80% lowers. Verify your local laws before purchasing. No FFL is needed for the shipment of this blank.
