Overview

The Premium 80% Lower Fire/Safe Marked – Billet is a precision-machined, unserialized lower receiver that requires final milling to become a functional firearm component. It is designed to accept standard mil-spec lower parts kits and buffer tube assemblies. The billet construction offers a tighter grain structure compared to forged receivers, resulting in a smoother surface finish and more consistent wall thickness. Each unit is inspected for critical dimensions including trigger pocket depth, pin hole alignment, and magazine well fitment. This is a parts category item intended for hobbyist fabrication and personal use.

• Material: 7075-T6 aluminum billet, Type III hard coat anodized in black for corrosion resistance and durability.
• Markings: Laser-etched “FIRE” and “SAFE” selector markings on both sides, with “PREMIUM” logo on the magazine well.
