RL556V3 80% AR15 Lower – OD Green

The RL556V3 80% AR15 Lower in OD Green represents a precision-machined foundation for the custom builder who demands exacting tolerances and material integrity. Designed for the AR-15 platform, this 80% lower receiver is forged from 7075-T6 aluminum and finished with a type III hard coat anodize in olive drab green. The RL556V3 designation indicates a specific generation of the receiver that incorporates reinforced trigger pocket geometry and optimized takedown pin lug clearances, providing a stable platform for both mil-spec and enhanced trigger groups. This component is not a functional firearm and requires additional machining to be completed into a finished receiver.

Overview

The RL556V3 80% AR15 Lower in OD Green is a raw forging that has been precisely profiled to remove 80% of the material required for a fully functional lower receiver. The remaining 20% of work—including trigger pocket milling, safety selector hole drilling, and takedown pin pocket finishing—is left to the end user. The receiver is manufactured from a single piece of 7075-T6 aluminum, heat-treated to MIL-A-8625F specifications, and then hard coat anodized in OD Green for corrosion resistance and colorfastness. The RL556V3 designation specifically refers to the v3 iteration of this lower, which features an enlarged trigger guard for gloved operation and a flared magazine well for faster reloads. The OD Green finish is applied using a type III anodize process that penetrates the aluminum surface, providing a durable coating that resists scratching and wear during handling and assembly.

Who It’s For

This product is intended for experienced builders who possess the necessary tooling—specifically a drill press or CNC router, appropriate end mills, and a finishing jig—to complete the final 20% of machining. The RL556V3 80% AR15 Lower in OD Green is suitable for individuals constructing a customized AR-15 for competition, recreational shooting, or personal defense applications. It is not recommended for first-time builders without prior machining experience, as improper milling can result in an unsafe or non-functional receiver. This component is designed for use by persons legally permitted to own and manufacture firearms under federal and state law. The OD Green finish is particularly suited for builders assembling a rifle with an earth-tone or woodland camouflage color scheme, as it coordinates with most OD Green and coyote brown furniture sets.
