Premium 80% Lower Fire/Safe Marked – Billet

When precision and compliance are non-negotiable, the Premium 80% Lower Fire/Safe Marked – Billet delivers a foundation built for the discerning builder. Machined from 7075-T6 aluminum billet, this lower receiver offers the rigidity and dimensional accuracy required for a tight, reliable fit with mil-spec upper receivers and parts kits. The fire/safe markings are laser-engraved to industry standard depth and placement, ensuring clarity through multiple finishing processes.

Overview

This premium 80% lower fire/safe marked – billet component arrives as an unfinished receiver requiring material removal in the trigger pocket, hammer pin, and selector areas. The billet construction eliminates casting porosity and provides a smoother surface finish than forged alternatives. Each unit is machined from a solid block of 7075-T6 aluminum and then hard-coat anodized to MIL-A-8625 Type III specifications, leaving the critical pocket areas in raw aluminum for your finishing work. The fire/safe markings are applied after anodizing using a laser etching process that will not chip or wear off during handling or finishing. This premium 80% lower fire/safe marked – billet is designed for builders who demand tight tolerances and a clean aesthetic without excess material flash or uneven wall thickness.
