Designed for builders who demand precision, this part integrates seamlessly into your project without requiring an FFL transfer for the raw component. The anodized black finish offers a durable, non-reflective surface that resists wear and corrosion, ensuring the markings remain legible over time. Whether you are completing a first build or adding to a collection, this 80% lower fire/safe marked – anodized black unit delivers a solid foundation for your lower receiver assembly.

Overview

This 80% lower fire/safe marked – anodized black component is a precision-machined part designed for use in custom AR-15 builds. It features clearly engraved fire and safe selector positions that are permanently marked into the material, not simply painted on. The anodized black coating provides a uniform matte finish that matches standard mil-spec upper receivers and handguards. As an 80% lower, this part requires final machining to complete the fire control pocket, making it a legal component for personal manufacture. The marking is applied with laser engraving technology, ensuring crisp, high-contrast letters that will not fade or peel under normal use.

Features & Specs

• Permanently laser-engraved “FIRE” and “SAFE” markings on anodized black surface for clear visual reference
• Manufacturer: 80% | Category: Parts | Compatible with standard AR-15 lower parts kits
• Anodized black Type III Class 2 finish per MIL-A-8625 for corrosion resistance and abrasion protection

The 80% lower fire/safe marked – anodized black component is manufactured from 7075-T6 aluminum billet, heat-treated for strength. The fire control pocket is left partially unmachined to comply with federal regulations for personal manufacture. The selector markings are positioned at industry-standard 90-degree and 180-degree rotations from the safety detent, allowing for drop-in compatibility with most AR-15 safety selectors. The anodized finish penetrates the aluminum surface, creating a hard outer layer that protects against scratches and solvent exposure.

Who It’s For

This product is intended for individuals who are legally permitted to manufacture firearms for personal use and possess the necessary tools and skills to complete the lower receiver. It is suitable for hobbyists, custom builders, and shooters who prefer to assemble their own platforms. The 80% lower fire/safe marked – anodized black is also appropriate for those who want a pre-marked lower that saves the step of applying their own selector indicators. Commercial users, gunsmiths performing work for others, or individuals in states with specific restrictions on unfinished receivers should verify local laws before purchase. This component is not a finished firearm and does not require an FFL transfer at the time of sale.
