Forged Fire/Safe Marked 80% Lower Assembly

This forged fire/safe marked 80% lower assembly provides the foundational platform for a custom AR-15 build without requiring a federal firearm license for purchase. Machined from a single 7075-T6 aluminum forging, this 80% lower assembly is designed for the builder who demands mil-spec geometry and precise fire/safe selector markings. The component arrives as an unfinished piece, allowing the end user to complete the machining process to their specifications. As a non-serialized part, it offers a legal pathway to a fully functional lower receiver once the trigger pocket, hammer and trigger pin holes, and selector detent channel are properly completed. This forged fire/safe marked 80% lower assembly is an essential starting point for the serious hobbyist or professional gunsmith looking to produce a reliable, custom firearm.

Overview

The forged fire/safe marked 80% lower assembly begins as a precision aluminum forging that is then machined to 80% completion. The receiver is heat-treated to T6 condition for optimal strength and dimensional stability. The forging process aligns the grain structure of the metal along the receiver contours, providing superior mechanical properties compared to billet units. The fire/safe markings are laser-etched into the lower receiver body, providing clear, permanent identification of selector positions. This component is intended for use with standard AR-15 upper receivers and parts kits, and it accepts all mil-spec trigger groups, grips, and stocks. The anodized black finish provides corrosion resistance and a consistent, professional appearance.

Features & Specs

• Material and Construction: Forged from 7075-T6 aluminum with a hard coat black anodized finish. The forging process ensures a dense, void-free structure that meets or exceeds mil-spec requirements for receiver strength and durability.
• Markings and Dimensions: Laser-etched fire/safe markings on both sides of the lower receiver. The assembly is machined to 80% completion, meaning the trigger pocket, hammer and trigger pin holes, and selector detent channel are not yet cut. All external dimensions conform to mil-spec standards for compatibility with standard AR-15 components.
• Compatibility and Use: Accepts standard AR-15 lower parts kits, buffer tube assemblies, and pistol grips. The 80% lower assembly is designed for use with a jig and appropriate tooling to complete the final machining steps. The fire/safe markings provide clear visual indication of selector lever positions after completion.

Who It’s For

This forged fire/safe marked 80% lower assembly is intended for individuals with the technical skill, tools, and knowledge to complete the final machining operations required to turn the unfinished component into a functional lower receiver. It is suitable for gunsmiths, custom builders, and hobbyists who want to create a personalized firearm without purchasing a serialized receiver. This product is not for the inexperienced user. The buyer must be legally eligible to possess firearms components and must comply with all federal, state, and local laws regarding the manufacture and ownership of firearms. The end user assumes full responsibility for completing the lower receiver in accordance with all applicable laws and regulations.
