RL556V3 80% AR15 Lower – Flat Dark Earth

Build your next AR-15 platform with precision and control using the RL556v3 80% AR15 Lower in Flat Dark Earth. This unfinished lower receiver is engineered for the serious builder who demands quality materials and exacting tolerances. As an 80% lower, it requires final machining to complete the fire control cavity, placing the responsibility of compliance and craftsmanship directly in your hands. The Flat Dark Earth finish provides a durable, corrosion-resistant surface that matches the most popular modern rifle aesthetics.

Overview

The RL556v3 80% AR15 Lower – Flat Dark Earth is a direct, mil-spec pattern 80% lower receiver designed for end users who prefer to complete their own firearm build from a partially machined blank. Manufactured by RL556v3, this component is classified as a parts category item under current ATF regulations. It is CNC machined from forged 7075-T6 aluminum, then Type III hard coat anodized in Flat Dark Earth. The 80% completion stage means the fire control pocket, trigger pin holes, and hammer pin holes are not yet machined, allowing the builder to customize the geometry to their preferred trigger and safety specifications.

Features & Specs

• Material & Construction: Forged from 7075-T6 aluminum, the same alloy used in mil-spec M16 receivers, ensuring high tensile strength and impact resistance. The Flat Dark Earth Type III hard coat anodizing provides a scratch-resistant, non-reflective finish that protects against environmental wear.
• Compatibility: Designed to accept standard mil-spec AR15 upper receivers, buffer tubes, and lower parts kits. The 80% blank includes all external dimensions identical to a finished lower, ensuring fitment with aftermarket grips, stocks, and trigger guards.
• Tolerances & Machining: The RL556v3 lower is machined to tight tolerances on the takedown pin lugs, magazine well dimensions, and trigger guard area. The pocket depth for the fire control group is left at 80% completion, with pilot marks for the trigger and hammer pin locations to guide your final drilling.

Who It’s For

This product is intended for experienced firearm builders who possess the necessary tools, knowledge, and legal compliance to complete an 80% lower receiver. You are a hobbyist, a gunsmith, or a custom builder who values the ability to select your own fire control group, safety selector, and trigger components. The RL556v3 80% AR15 Lower in Flat Dark Earth is not for first-time builders who lack machining experience; it requires a drill press or CNC mill, appropriate jigs, and careful measurement to complete the fire control cavity and pin holes. You accept full responsibility for the legality of the finished firearm under all applicable federal, state, and local laws.
