80% Lower Fire/Safe Marked – Anodized Black

If you are building a custom AR-15 from the ground up, the lower receiver is the foundation. And when you are starting with an 80% lower, the markings matter. This 80% lower fire/safe marked – anodized black unit delivers the clean, factory-style selector engravings you need before you finish the pocket and trigger group. No guesswork on positioning, no aftermarket jigs for engraving. The safety markings are already laser-etched and ready to go.

Overview

This 80% lower fire/safe marked – anodized black receiver is precision machined from billet 7075-T6 aluminum. It is a raw 80% blank, meaning the fire control pocket is not fully milled, and the hammer and trigger pin holes are not drilled. You complete the machining yourself or with a qualified shop. The anodized black finish is MIL-SPEC hard coat, providing consistent corrosion resistance and a uniform appearance that matches standard mil-spec uppers. The selector markings are deep enough to remain visible after cerakote or additional finishing, but subtle enough to maintain a clean professional look.

Features & Specs

• Material: 7075-T6 aluminum billet, heat-treated and stress-relieved for dimensional stability during your machining process.
• Markings: Laser-etched “FIRE” and “SAFE” in standard AR-15 orientation, precisely located for compatibility with mil-spec selectors and detents.
• Finish: Type III Class 2 hard coat anodized black per MIL-A-8625. Consistent, durable, and ready for your jig setup.
• Compatibility: Accepts all standard AR-15 lower parts kits, buffer tubes, and stocks once fully machined.
• Manufacturer: 80% | Category: Parts

Who It Is For

This 80% lower fire/safe marked – anodized black is built for the hands-on builder who values accuracy and efficiency. Whether you are a first-time builder using a router jig or a seasoned machinist running a CNC, the pre-marked selector engravings save you an entire step. You do not need to buy a separate engraving fixture or send the lower out for laser work after machining. It is also ideal for those who prefer not to have blank, unmarked receivers. The fire/safe markings give the finished rifle a complete, professional appearance without adding cost or complexity. If you are assembling a pistol or rifle configuration, the markings are universal and do not conflict with any brace or stock setup.
