Forged Fire/Safe Marked 80% Lower Assembly

This forged fire/safe marked 80% lower assembly provides the foundational platform for builders seeking a mil-spec starting point without the requirements of a serialized receiver. Constructed from 7075-T6 aluminum, this un-machined lower is designed to accept standard AR-15 upper components once the trigger pocket, fire control group holes, and safety selector detent channel are completed by the end user. The fire/safe markings are roll-stamped into the receiver prior to anodizing, ensuring durability and legibility through the entire build process.

Overview

The forged fire/safe marked 80% lower assembly is manufactured to mil-spec dimensions, offering a true 80% completion stage that requires finishing the fire control cavity and related machining steps. This lower is compatible with all standard AR-15 mil-spec lower parts kits, buffer tubes, and stocks. The receiver is heat-treated to T6 condition and hard coat anodized per MIL-A-8625F, Type III, Class 2 specifications for corrosion resistance and wear protection. Each unit is individually inspected for dimensional accuracy against mil-spec gauges before packaging.

Features & Specs

• Material: 7075-T6 aluminum forging; heat treated and hard coat anodized to MIL-A-8625F Type III, Class 2
• Markings: Roll-stamped fire/safe selector engravings on both sides; non-reflective black anodized finish
• Dimensions: 80% completion state; requires machining of trigger pocket, hammer pin holes, trigger pin holes, and safety selector hole

This forged fire/safe marked 80% lower assembly includes the integral trigger guard and is compatible with all standard AR-15 lower parts kits. The pocket dimensions are within 0.005 inches of mil-spec tolerances, allowing precise finishing with standard jigs and router setups. The rear takedown pin lug and buffer tower are fully formed to accept standard carbine or rifle buffer systems. The fire/safe markings are positioned at standard 90-degree and 45-degree orientations for compatibility with mil-spec safety selectors.

Who It’s For

This assembly is designed for experienced builders who possess the tooling and knowledge to complete a lower receiver from an 80% stage. It is suitable for gunsmiths, hobbyists, and individuals constructing a custom AR-15 pattern rifle who require a receiver with clear, permanent fire/safe markings. Builders should have access to a drill press, router with appropriate bits, and a jig system designed for AR-15 lower completion. This component is not intended for first-time builders without prior machining experience or proper safety equipment. The forged fire/safe marked 80% lower assembly requires the user to complete all fire control group cavities and function check the safety selector engagement before assembly into a functional firearm.
