Premium 80% Lower Fire/Safe Marked – Billet

For the serious builder who demands precision and clarity in every component, the Premium 80% Lower Fire/Safe Marked – Billet delivers exactly what the spec sheet promises. Machined from billet 7075-T6 aluminum, this unmarked lower receiver blank provides a clean, unblemished canvas for your custom build, while the laser-etched fire/safe markings ensure your finished rifle meets both functional and aesthetic standards. At an accessible price point, this is the foundation for a reliable, code-compliant AR-15 platform without unnecessary frills.

Overview

The Premium 80% Lower Fire/Safe Marked – Billet is a precision-machined receiver blank that requires final milling to complete. Manufactured from solid billet aluminum, it offers superior grain structure and dimensional consistency compared to forged alternatives. The fire/safe selector markings are laser-etched into the lower receiver body, providing clear, permanent visual reference for selector positions once your build is complete. This component is classified as a firearm part, not a finished receiver, and requires additional machining to become functional.

Every Premium 80% Lower Fire/Safe Marked – Billet is manufactured to industry-standard dimensions, ensuring compatibility with aftermarket components. The billet construction eliminates the parting lines and tooling marks common to forged lowers, giving you a cleaner base for custom finishes or coatings. The fire/safe markings are positioned at the standard selector location and are visible through most aftermarket grips and safety selectors.

Who It’s For

This product is designed for experienced builders who require a high-quality foundation for a custom AR-15 project. It suits hobbyists who prefer billet receivers for their aesthetic consistency, as well as gunsmiths who need a reliable, repeatable platform for client builds. The fire/safe markings make it ideal for builders who prioritize clear selector indication without relying on aftermarket marking tools or stencils. This is not a beginner-level component; it requires access to a drill press or milling machine, jigs, and knowledge of 80% lower finishing procedures.

Shipping & FFL

This Premium 80% Lower Fire/Safe Marked – Billet is classified as a firearm part, not a finished receiver. As such, it ships directly to your residence without requiring transfer through a Federal Firearms License (FFL) holder. However, once machining is completed to the point where the lower can accept a fire control group, it becomes a firearm under federal law. If you later sell or transfer the completed receiver, you must comply with all applicable federal, state, and local laws. Some states and localities impose restrictions on 80% lowers—check your jurisdiction before ordering. By purchasing, you confirm you are legally eligible to own firearms and that your state allows possession of unfinished receivers.
