Rl556V3 80% AR15 Lower – Flat Dark Earth

The RL556v3 80% AR15 Lower in Flat Dark Earth represents a precision-machined foundation for the serious builder who demands control over every component of their rifle. Manufactured by RL556v3, this 80% lower receiver is designed to meet the exacting standards of the firearms industry, providing a clean, unmarked platform that requires final machining to become a functional firearm. Engineered from high-grade aluminum alloy with a durable Type III hard coat anodized finish in Flat Dark Earth, this lower offers corrosion resistance and a consistent, tactical appearance that integrates seamlessly with standard AR15 upper assemblies and mil-spec parts kits.

Overview

The RL556v3 80% AR15 Lower – Flat Dark Earth is a manufacturer-direct component from RL556v3, categorized under Parts. It is specifically designed for the end user who wishes to complete the lower receiver at home or in a shop setting. The 80% designation means the lower is not yet a firearm under federal regulations; it lacks critical fire control cavities and requires drilling and milling to be functional. This allows the builder to legally produce a firearm for personal use without serialization, provided all local, state, and federal laws are followed. The Flat Dark Earth finish is applied using a matte anodizing process that reduces glare and provides a non-reflective surface suitable for field use.

Features & Specs

• Material and Finish: Constructed from 7075-T6 aluminum with a Type III hard coat anodized finish in Flat Dark Earth. This provides high tensile strength, impact resistance, and long-term protection against environmental elements.
• Manufacturing Tolerances: Machined to mil-spec dimensions for compatibility with standard AR15 upper receivers, buffer tubes, and lower parts kits. The RL556v3 80% AR15 lower features a reinforced pocket area and a flared magazine well for improved reloading speed.
• Compatibility: Accepts all standard AR15 fire control groups, grips, stocks, and buffer systems. The 80% blank includes pre-drilled takedown pin holes, a trigger guard area, and a receiver extension threading point, but requires the end user to complete the trigger pocket, hammer pin holes, and selector detent channel.

The RL556v3 80% AR15 Lower – Flat Dark Earth is a clean, unmarked receiver that does not include any serial number or manufacturer markings, giving the builder full discretion over identification. The anodized finish is applied evenly across all surfaces, including the magazine well and trigger guard area, ensuring no raw aluminum is exposed after final machining.

Who It's For

This product is intended for experienced firearm builders, hobbyists, and gunsmiths who have the necessary tools, knowledge, and skill to complete an 80% lower receiver. It is not a drop-in component and requires drilling, milling, and finishing work. The RL556v3 80% AR15 Lower is ideal for those who wish to build a custom rifle from the ground up, control the quality of every part, or create a firearm that is not subject to federal serialization requirements. It is also suitable for training environments where multiple lowers are needed for practice builds. This component is not intended for first-time builders without proper instruction or access to a dedicated jig and router setup.

Shipping & FFL

However, it is your responsibility to verify that possession and subsequent completion of an 80% lower receiver are legal under all applicable federal, state, and local laws. Some states and municipalities impose restrictions on the purchase, possession, or machining of 80% lowers. By purchasing this item, you acknowledge that you are legally eligible to own and complete a firearm, and that you will comply with all laws regarding the final product. We recommend consulting with a qualified attorney if you have any questions about the legality of this component in your jurisdiction.
