RL556V3 80% AR15 Lower – Gray

The RL556V3 80% AR15 Lower – Gray represents a foundational component for the serious builder who demands precision from the ground up. Machined from billet 7075-T6 aluminum, this 80% lower receiver is designed for those who understand the importance of starting with a clean, true platform. The gray cerakote finish provides a durable, non-reflective surface that resists wear and corrosion, ensuring your build maintains its integrity through range sessions and field use. This is not a novelty item; it is a functional workpiece intended for experienced individuals who choose to complete their own firearm for personal use.

Overview

The RL556V3 80% AR15 Lower – Gray is a pre-machined receiver that requires final milling to accept standard AR15 fire control groups and components. Designed to strict mil-spec tolerances, this lower offers a consistent foundation for a reliable build. The gray finish is a factory-applied cerakote that stands up to harsh solvents and heavy handling, making it a practical choice for a duty-grade or competition firearm. This component is sold as an unfinished workpiece and is not a firearm; it does not require an FFL transfer at the time of purchase.

Features & Specs

• Material and Construction: Machined from solid 7075-T6 billet aluminum for superior strength and rigidity. The RL556V3 80% AR15 lower – gray features a hard-coat anodized base beneath the cerakote finish for added corrosion resistance.
• Finish: Factory-applied gray cerakote coating provides a consistent, low-glare surface that resists scratches, chemicals, and UV degradation. The finish is uniform across the entire receiver, including the trigger guard and grip area.
• Compatibility: Designed to accept all standard AR15 upper receivers, buffer tubes, and lower parts kits. The trigger pocket and safety selector holes are pre-drilled to spec, requiring only the removal of the trigger pocket material and fire control group shelf to complete the receiver.
