Description

RL556v3 80% AR15 Lower – Flat Dark Earth

The RL556v3 80% AR15 Lower in Flat Dark Earth represents a precision-machined foundation for builders seeking a durable, mil-spec platform. This 80% lower receiver is designed for those who prefer to complete their own firearm from a raw component, offering the flexibility to customize the fire control group and final finishing. Constructed from 7075-T6 aluminum, the RL556v3 80% AR15 Lower – Flat Dark Earth is a rugged, corrosion-resistant base for your next AR-15 build.

Overview

The RL556v3 80% AR15 Lower – Flat Dark Earth is an unfinished lower receiver that requires additional machining to become a functional firearm component. It is manufactured to exacting tolerances, ensuring compatibility with standard AR-15 upper receivers, buffer tubes, and lower parts kits. The Flat Dark Earth finish provides a low-reflectivity surface that resists wear and matches a wide range of tactical and hunting configurations. As a true 80% lower, it allows the builder to legally complete the receiver without a serial number, subject to federal and state regulations. This part is classified under the Parts category and is built to the same specifications as fully finished receivers, minus the fire control pocket and trigger pin holes.

Features & Specs

  • Material: 7075-T6 aluminum for high strength and impact resistance with a hard-coat anodized Flat Dark Earth finish.
  • Specifications: Mil-spec dimensions with a fully machined magazine well, rear takedown pin lug, and buffer tube threads. The RL556v3 80% AR15 Lower – Flat Dark Earth requires final drilling for the trigger, hammer, and selector pins.
  • Compatibility: Accepts all standard AR-15 lower parts kits, pistol grips, buttstocks, and buffer assemblies. Designed for use with .223 Remington/5.56 NATO calibers.

Manufactured by RL556v3, this lower receiver is consistent with industry-standard tolerances. The Flat Dark Earth color is achieved through a Type III Class 2 anodizing process, providing a durable, non-reflective surface. The RL556v3 80% AR15 Lower – Flat Dark Earth includes a threaded bolt catch area and a compatible trigger guard, though the trigger guard is not installed. All critical external surfaces are fully finished, while the fire control pocket remains untouched for the builder to complete.

Who It’s For

The RL556v3 80% AR15 Lower – Flat Dark Earth is intended for experienced firearm builders and hobbyists who want to create a custom AR-15 from a raw receiver. It is ideal for individuals who have the tools and knowledge to complete the fire control pocket and pin holes, requiring a drill press, jig, and appropriate end mills. This product is not suitable for first-time builders without proper training, as improper machining can render the lower receiver non-functional. It is designed for those who appreciate the craftsmanship of finishing their own lower receiver and want a durable, mil-spec base in Flat Dark Earth. The RL556v3 80% AR15 Lower – Flat Dark Earth is also a practical choice for builders who wish to avoid serialization where legally permitted, provided they comply with all applicable laws.

Shipping & FFL

This RL556v3 80% AR15 Lower – Flat Dark Earth is not classified as a firearm by the ATF because it is not yet in a functional state. Therefore, it can be shipped directly to your residence without an FFL transfer. However, check your local and state laws before ordering, as some jurisdictions regulate 80% receivers as firearms. You are responsible for completing the machining in accordance with federal, state, and local regulations. Once the RL556v3 80% AR15 Lower – Flat Dark Earth is completed, you must comply with all applicable laws regarding ownership and serialization. No FFL is required for the purchase of this 80% lower receiver, but we strongly recommend consulting legal counsel if you have any questions about the legality of building your own firearm.
