80% Lower Fire/Safe Marked – Anodized Black

If you are building from the ground up, the little details matter just as much as the big ones. The 80% lower fire/safe marked – anodized black is a straightforward, no-nonsense component for your next project. Whether you are finishing an 80% receiver or just replacing a stripped lower, this part gives you clear, crisp selector markings that align with standard safety positions. It is machined from billet 7075-T6 aluminum and given a mil-spec anodized black finish that holds up to handling and solvent exposure. No logos, no frills, just the correct fire and safe engraving you need for a clean, functional build.

Overview

This is a bare 80% lower receiver that has been pre-marked with fire and safe indicators on both sides. The markings are laser engraved for durability and are positioned to match standard AR-15 selector travel. The anodized black finish is consistent and non-reflective, making it a solid choice for both duty-oriented builds and range toys. Because it is an 80% lower, it requires machining to complete the fire control pocket before it can accept a trigger group and safety selector. This part is sold as a raw component and is not a functional firearm until fully finished.

The 80% lower fire/safe marked – anodized black is designed to work with any mil-spec safety selector. The fire and safe positions are clearly indicated, so you can install your preferred safety and instantly verify function during assembly. The anodized finish resists scratching during machining and handling, and the engraving will not wear off with normal use. This is a component that does exactly what it says on the tin: provides a clean, marked platform for your build.

Who It’s For

This part is for the builder who wants clear safety markings without paying for a fully engraved lower. It is ideal for hobbyists who prefer to finish their own receivers at home or in a small shop. If you are assembling a spare lower for a future upper, or if you want to match the anodized black finish of your existing parts kit, this is a practical choice. It is also a good option for those who prefer a minimalist look without rollmarks or logos, but still want functioning fire and safe indicators. If you are building for competition, training, or general range use, this marked lower gives you a clean starting point.

Shipping & FFL

Because this item is sold as an 80% lower receiver, it is not considered a firearm under federal law and does not require shipment to an FFL dealer. It can be shipped directly to your residence or business address. However, federal, state, and local laws regarding unfinished receivers vary. It is your responsibility to verify that possession and finishing of this component is legal in your jurisdiction. Once you complete the receiver, it becomes a firearm and must be serialized in accordance with applicable law. No FFL transfer is required for the purchase of this part, but we recommend checking your local regulations before ordering.
