RL556V3 80% AR15 Lower – Gray

Overview

The RL556V3 80% AR15 Lower – Gray is a precision-machined component designed for builders who demand exacting tolerances and a clean, factory-grade finish. Manufactured by RL556V3, this 80% lower receiver is produced from 7075-T6 aluminum and features a durable Type III hard coat anodized finish in gray. As a raw 80% lower, it requires final machining of the fire control pocket and trigger pin holes before assembly, allowing the builder to complete a legally compliant firearm without a serialized transfer. This model is categorized as a parts component and is intended for use in custom AR15 builds where the user assumes responsibility for final fabrication.
