Forged Fire/Safe Marked 80% Lower Assembly

When building a precision AR-15 platform, the foundation matters. The Forged Fire/Safe Marked 80% Lower Assembly is a mil-spec component designed for builders who require a properly marked, unfinished lower receiver. Machined from a 7075-T6 aluminum forging, this assembly provides the structural integrity and dimensional accuracy needed for a reliable firearm build. The fire/safe markings are roll-marked directly into the aluminum, ensuring durability and clear legibility throughout the life of the build.

Overview

The Forged Fire/Safe Marked 80% Lower Assembly is an unfinished lower receiver that requires final machining to become a functional component. It is manufactured from a certified 7075-T6 aluminum forging and anodized to MIL-A-8625F Type III Class 2 hard coat spec. The lower is marked with standard selector positions—SAFE and FIRE—along with “SEMI” and “AUTO” indicators for compatibility with standard lower parts kits. This assembly is precisely machined to 80% completion, leaving the trigger pocket, hammer pin holes, and fire control group cavity partially formed for the end user to finish.
