Overview

This 80% lower receiver is a blank canvas for the dedicated builder. It is classified as a part and requires finishing (milling of the fire control pocket, trigger slot, and selector detent) before it can accept standard AR15 lower parts kits. The RL556v3 brand is known for tight tolerances and consistent hard-coat anodizing, ensuring your finished build functions reliably. The gray finish offers a clean, low-glare aesthetic that pairs well with both classic black and FDE upper components. As a rl556v3 80% ar15 lower – gray, it meets all standard mil-spec dimensions for compatibility with aftermarket stocks, grips, and triggers.

• Finish: Type III Class 2 hard-coat anodized in gray for corrosion resistance and a uniform matte appearance.
• Specifications: Unfinished (80%) lower receiver; requires drilling of trigger, hammer, and selector pin holes; compatible with all standard AR15 lower parts kits.

Each rl556v3 80% ar15 lower – gray is inspected for critical dimensions before packaging. The magazine well is fully machined, and the rear takedown lug is pre-threaded.

For builders who prioritize precision and finish consistency, this lower is a reliable choice.

Who It’s For
