80% Lower Fire/Safe Marked – Anodized Black

If you are building a custom AR platform from the ground up, the details matter. The selector markings on your lower receiver are more than just aesthetics; they are the interface between you and your rifle’s function. This 80% Lower Fire/Safe Marked in anodized black delivers the clean, factory-style engraving you expect, without the pre-machined fire control pocket. It is a blank canvas for the dedicated builder who wants a professional look from the start.

Overview

This 80% lower features crisp, laser-engraved “FIRE” and “SAFE” markings on the selector side, finished in a durable MIL-SPEC Type III hard coat anodized black. The anodizing is consistent and deep, matching the finish of most upper receivers and handguards on the market. Because it is an 80% receiver, it requires final machining of the trigger pocket and fire control group area before it can accept a lower parts kit. The markings are correctly positioned for standard AR-15 selectors, giving you a clean, factory-correct appearance once your build is complete.

Features & Specs

• 80% Lower Fire/Safe Marked – Anodized Black: Pre-engraved selector markings eliminate the need for custom stenciling or laser work after your build is finished. The anodized black finish resists wear, corrosion, and solvents.
• Material and Construction: Forged from 7075-T6 aluminum, this receiver is heat-treated and hard coat anodized per MIL-A-8625 Type III. The pocket is left unmachined to comply with federal regulations regarding unfinished firearm receivers.
• Compatibility: Accepts standard AR-15 lower parts kits, buffer tubes, and pistol grips. Designed to work with mil-spec upper receivers. Markings are set for a standard semi-auto safety selector.

Who It’s For

This part is for the hands-on builder who prefers to complete their own machining rather than purchase a finished receiver. It is ideal for someone comfortable with a drill press, jig, and end mill, who wants the satisfaction of saying “I built this.” The fire/safe markings are a practical touch for builders who want their finished rifle to look like a factory production piece, without the extra cost of a separate engraving service. It is also a smart choice for those assembling multiple lowers, as the consistent markings speed up the build process.

Because this is an 80% lower, it is not a firearm and can be shipped directly to your door without an FFL transfer. This simplifies logistics for the builder, but remember that once you complete the machining, it becomes a firearm under federal law and must be treated as such. The 80% lower fire/safe marked anodized black receiver is a reliable foundation for a personal build project. Whether you are a first-time builder or an experienced machinist, this blank gives you a professional start.

Shipping & FFL

This product is not a firearm. It is classified as an unfinished receiver and may be shipped directly to your residence without a Federal Firearms License (FFL) transfer. You do not need to involve a dealer for delivery. However, you must verify that your local and state laws allow possession of unfinished receivers. Some states and municipalities have specific restrictions. It is your responsibility to comply with all applicable laws. Once you complete the machining and assemble the lower into a functional firearm, it must be marked in accordance with ATF regulations if you intend to sell or transfer it. For personal use, marking requirements vary; consult your local laws.
