RL556v3 80% AR15 Lower – Flat Dark Earth

The RL556v3 80% AR15 Lower in Flat Dark Earth represents a precision-machined foundation for the custom AR-15 builder. Manufactured by RL556v3, this 80% lower receiver is designed for the enthusiast seeking a durable, mil-spec compatible platform. Constructed from forged 7075-T6 aluminum and finished in a durable, corrosion-resistant Flat Dark Earth anodized coating, this component provides the structural integrity required for a reliable build. As an 80% lower, it requires final machining to be completed by the end user, offering flexibility in the build process while remaining a cost-effective starting point for your next AR-15 project.

Overview

The RL556v3 80% AR15 Lower is a semi-finished component that brings military-specification tolerances to the civilian builder. This part is precisely forged and machined to the 80% completion stage, meaning the fire control group pocket, trigger slot, and safety selector holes are unfinished. The Flat Dark Earth finish is applied via Type III hard coat anodizing, ensuring resistance to wear, scratches, and environmental exposure. This lower receiver is compatible with standard AR-15 upper receivers, parts kits, and buffer tube assemblies, making it a versatile foundation for a wide range of build configurations. Whether you are constructing a lightweight carbine, a precision rifle, or a dedicated pistol-caliber platform, the RL556v3 provides the necessary dimensional accuracy and material quality to support your goals.

This RL556v3 80% AR15 Lower is designed to be finished using standard jigs and router or drill press setups. The Flat Dark Earth anodized finish is applied after all preliminary machining, ensuring the coating remains intact through the final milling process. The receiver is marked with standard selector positions and includes the RL556v3 manufacturer rollmark for authenticity.

Who It’s For

This RL556v3 80% AR15 Lower is intended for experienced builders who own the necessary tools and knowledge to complete the final machining. It is ideal for the hobbyist who values hands-on assembly and wants to create a firearm from a blank slate. The Flat Dark Earth finish suits those looking to match a specific color scheme or build a rifle with a tactical aesthetic. This product is not for first-time builders lacking access to proper fixturing and machining equipment. It is designed for individuals in compliance with all applicable federal, state, and local laws regarding the manufacture of firearms for personal use. The RL556v3 lower is a precision component for those who prioritize material quality and dimensional consistency in their builds.

Shipping & FFL

This RL556v3 80% AR15 Lower is not classified as a firearm by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) because it is not yet in a functional state. Therefore, it does not require transfer through a Federal Firearms License (FFL) dealer. It can be shipped directly to your address. However, it is your responsibility to verify that possession and completion of an 80% lower receiver is lawful in your jurisdiction. Some states and municipalities have restrictions on unfinished receivers. By purchasing this product, you acknowledge that you are legally permitted to own and complete this component. Once machined into a functional firearm, it must comply with all applicable federal and state laws, including serialization requirements if applicable in your area. Check local regulations before ordering.
