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

Overview

This product listing is for a blemished – 80% lower fire/safe marked – anodized black component intended for custom firearm builds. As an 80% lower receiver, it requires additional machining to be completed into a functional firearm receiver. The part is sold in its current unfinished state and includes the standard fire/safe selector markings engraved into the lower receiver body. The anodized black finish is MIL-SPEC grade, though minor cosmetic blemishes are present from the manufacturing process. These blemishes do not affect structural integrity or dimensional accuracy. This is a cost-effective option for builders who prioritize function over cosmetic perfection. Each unit is individually inspected to ensure all critical dimensions remain within specification. The blemished – 80% lower fire/safe marked – anodized black unit is machined from 7075-T6 aluminum billet and is compatible with standard mil-spec upper receivers and lower parts kits. No warranty is provided regarding cosmetic appearance due to the blemished nature of the product.

The blemished – 80% lower fire/safe marked – anodized black receiver is designed for builders with access to a drill press, jig, and end mill. All critical pin holes are pre-drilled to within 0.001 inch of specification. The anodized coating is fully intact on all functional surfaces, with blemishes limited to external cosmetic areas. Threads in the grip screw and buffer tube areas are clean and pass go/no-go gauge inspection. This part is classified as a non-firearm component under current ATF regulations and may be shipped directly to your door without an FFL transfer for the unfinished item.

Who It’s For

This product is intended for experienced firearm builders who can complete the final machining steps required to finish the lower receiver. The blemished – 80% lower fire/safe marked – anodized black component suits builders who want a fully functional lower receiver with standard selector markings at a reduced cost. It is appropriate for hobbyists building a single rifle or for small-scale builders purchasing multiple units for custom projects. The cosmetic blemishes are cosmetic only and do not affect the ability to assemble a reliable firearm. Beginners should be aware that completing an 80% lower requires specific tools, a stable workbench, and familiarity with receiver dimensions. If you are building a rifle for competition, defense, or recreational shooting, this lower provides the same functional base as a fully finished receiver after proper completion. The fire/safe markings are clearly engraved and will remain visible after final assembly.
