Overview

This 80% lower fire/safe marked – anodized black is not a firearm and may be shipped directly to your door. It requires machining to complete the fire control cavity and trigger pin holes. The receiver is CNC machined from 7075-T6 aluminum and finished with a Type III Class 2 anodized black coating. The fire/safe markings are laser-etched into the lower receiver, providing a professional look without the need for additional stamping. This product is ideal for builders who want a functional and visually consistent lower without paying for a fully assembled receiver.

Features & Specs

• Material: 7075-T6 aluminum with Type III Class 2 anodized black finish

This 80% lower fire/safe marked – anodized black includes the following specifications from the manufacturer:

The fire/safe markings are machined into the aluminum before anodizing, ensuring they remain legible through the finishing process. The receiver is designed to accept all standard AR-15 components, including triggers, bolt catches, and magazine releases. The anodized black surface is non-reflective and resistant to wear, making it suitable for both range use and field conditions.

Who It’s For

This product is intended for hobbyists, DIY builders, and gunsmiths who want to complete a lower receiver at home using a jig and router or drill press. The 80% lower fire/safe marked – anodized black is also suitable for those who prefer to have a gunsmith finish the machining process. It is not for those seeking a fully assembled, serialized receiver. If you are building a rifle from scratch or replacing a lower on an existing upper, this component provides a cost-effective starting point without the need for a background check at the time of purchase.
