RL556V3 80% AR15 Lower – Gray

The RL556V3 80% AR15 Lower – Gray represents a precision-machined foundation for builders who demand exacting standards. Manufactured by RL556v3, this raw 80% lower receiver is designed for the serious hobbyist or small-scale manufacturer seeking a clean, unmarked platform. The gray anodized finish offers a professional appearance while maintaining the durability required for a long-service life. This component is sold as an unfinished receiver requiring additional machining to be functional. It is not a firearm and may be shipped directly to your door.

Overview

The RL556V3 80% AR15 Lower – Gray is a direct-mil-spec pattern lower receiver that provides a true-to-spec platform for your next AR15 build. Constructed from 7075-T6 aluminum, this lower offers the same material and heat-treat standards found in production firearms, without the serialization or regulatory paperwork. The gray hardcoat anodized finish resists wear and corrosion while blending with both black and FDE component schemes. With the RL556v3 name behind it, you are working with a component that maintains consistent wall thickness, correctly located trigger pin holes, and precise safety selector detent channels.

Features & Specs

• Mil-spec 7075-T6 aluminum construction with hardcoat anodized gray finish for corrosion resistance and dimensional stability.
• Compatible with all standard AR15 upper receivers, buffer tubes, and trigger groups; no proprietary parts required.
• Pre-machined trigger guard area and rear takedown pin detent hole for easier final assembly.

The RL556V3 80% AR15 Lower – Gray features a fully machined pocket with only the fire control cavity, trigger slot, and safety selector holes left for you to complete. The lower includes a reinforced front pivot pin lug and a flared magazine well for easier reloads. All critical dimensions are held to within .001 inch of mil-spec drawings, ensuring your completed build functions reliably with standard AR15 components. The gray finish is applied after machining to prevent any bare aluminum exposure in the pocket areas.

Who It’s For

This RL556V3 80% AR15 Lower – Gray is designed for experienced home builders, gunsmiths, and small firearms manufacturers who possess the necessary tooling and skill to complete an 80% receiver. You should be comfortable using a drill press, end mill, or CNC router to machine the remaining material. This product is not for first-time builders or those without access to proper fixturing and cutting tools. It is ideal for individuals who wish to create a firearm for personal use without a serial number, in compliance with all applicable federal, state, and local laws. The gray finish provides an alternative to standard black for builders who want a distinct look without sacrificing durability.

Shipping & FFL

Because the RL556V3 80% AR15 Lower – Gray is not a firearm and does not contain a serial number, it may be shipped directly to your residence or business address without involving a Federal Firearms License (FFL) holder. No background check is required for purchase. However, you are solely responsible for verifying that possession and completion of an 80% lower receiver is legal in your jurisdiction. Some states and localities impose restrictions on the ownership or machining of unserialized receivers. By purchasing this product, you confirm that you are legally permitted to own and complete a non-serialized firearm component in your area. This product is sold as a raw piece of metal requiring significant machining and is not functional as received. All sales are final; no returns are accepted on machined components.
