Premium 80% Lower Fire/Safe Marked – Billet

The premium 80% lower fire/safe marked – billet represents a cornerstone component for builders who demand precision from the ground up. Machined from certified 7075-T6 aluminum billet stock, this lower receiver blank is engineered to meet the exacting tolerances required for a reliable, durable firearm platform. The integrated fire/safe selector markings are laser-etched after anodizing, ensuring legibility through repeated handling and cleaning cycles. Designed for the serious builder, this component provides the foundation for a custom rifle that performs under the most demanding conditions.

Overview

This premium 80% lower fire/safe marked – billet begins as a solid block of aircraft-grade aluminum, then undergoes a multi-axis CNC machining process to achieve its final geometry. The billet construction eliminates the inconsistencies found in forged receivers, delivering a straighter, truer platform from the start. The fire/safe markings are permanently applied using a high-contrast laser engraving process, clearly indicating selector positions without the risk of fading or wear. Each unit is individually inspected for dimensional accuracy, thread quality, and surface finish before packaging. The result is a component that offers the builder a superior starting point for a precision firearm.

Features & Specs

• Material: 7075-T6 aluminum billet, heat-treated to Mil-Spec hardness standards for maximum structural integrity under high-round-count use.
• Markings: Laser-etched fire/safe selector indicators on both sides; markings are filled with a durable white pigment for high visibility in low-light environments.
• Machining: Fully CNC-machined from a single billet with squared front and rear take-down pin lugs, eliminating the need for hand-fitting in most complete upper receiver assemblies.
• Finish: Type III Class 2 hard coat anodized per MIL-A-8625F, providing a wear-resistant surface that resists corrosion, scratches, and solvent damage.
• Specifications: 80% completion state with un-machined trigger pocket, hammer pin holes, and safety selector hole; jig-ready geometry compatible with standard 80% lower jigs.
• Weight: Approximately 12.5 ounces (unfinished), offering a balance between strength and overall rifle weight.

Who It’s For

The premium 80% lower fire/safe marked – billet is intended for the experienced builder who values precision over expedience. This component is not for first-time builders or those seeking a quick assembly. It is designed for individuals who possess the tools, knowledge, and patience to complete the fire control pocket and selector holes to exact specifications. The billet construction and fire/safe markings serve the shooter who requires a consistent, repeatable platform for competition, training, or custom builds where every thousandth of an inch matters. If you are a builder who treats the lower receiver as the foundation of accuracy, this blank provides the structural fidelity you require.
