Forged Fire/Safe Marked 80% Lower Assembly

Engineered for precision builders and custom firearm enthusiasts, the Forged Fire/Safe Marked 80% Lower Assembly represents a foundational component for any AR-platform project. This un-machined lower receiver is manufactured from a single 7075-T6 aluminum forging, ensuring structural integrity and dimensional consistency throughout the finishing process. The receiver is clearly marked with standard fire and safe selector indicators, providing a clean, professional aesthetic once the build is complete. As a raw 80% component, this assembly requires final machining of the trigger pocket and fire control group pocket before it can be assembled into a functional firearm. Each lower is produced to mil-spec dimensions, allowing compatibility with a wide range of aftermarket upper receivers, buffer tubes, and fire control parts. The Forged Fire/Safe Marked 80% Lower Assembly is an ideal starting point for those who demand quality material and accurate markings in their build process.

Overview

The Forged Fire/Safe Marked 80% Lower Assembly is a precision-forged, semi-finished receiver blank intended for personal manufacturing. It is produced using a hot die forging process that aligns the grain structure of the 7075-T6 aluminum for maximum strength. The receiver comes with all critical external dimensions already machined to spec, including the takedown pin holes, trigger guard area, and magazine well. The fire/safe markings are laser-engraved for durability and visibility. This lower assembly requires the end user to complete the pocket milling for the trigger group and hammer, as well as drilling for the selector detent and bolt catch pin. It is classified as a non-firearm component under federal regulation, as it is not yet in a functional state.

Who It’s For

This Forged Fire/Safe Marked 80% Lower Assembly is designed for experienced hobbyists, gunsmiths, and custom builders who possess the necessary tooling and knowledge to complete a firearm receiver from a raw forging. It is suitable for individuals who wish to build a personalized AR-15 platform rifle or pistol from the ground up, selecting their own trigger group, grip, stock, and upper components. The component is not intended for first-time builders without access to a drill press, mill, or jig system, as precision machining is required to achieve safe and reliable function. It is also appropriate for those who prefer a lower that is clearly marked with standard fire/safe indicators rather than unmarked or generic blanks.

Shipping & FFL

This product is an unfinished 80% lower receiver and is not considered a firearm by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
