RL556v3 80% AR15 Lower – White

The rl556v3 80% ar15 lower – white offers builders a precision-machined foundation for custom AR15 platform builds. Designed for hobbyists and gunsmiths who require a clean, unfinished lower receiver, this component arrives ready for final machining. The white anodized finish provides a neutral base suitable for cerakote or paint application, while the 80% completion stage ensures compliance with federal regulations regarding unfinished receivers. Each unit is crafted from 7075-T6 aluminum, providing a durable, corrosion-resistant platform consistent with mil-spec tolerances.

Overview

This rl556v3 80% ar15 lower – white is manufactured by RL556v3, a brand recognized for producing AR15 components that meet standard dimensional specifications. The lower receiver is machined to 80% completion, meaning the fire control cavity, trigger pocket, and buffer tube threads are unfinished. The white anodized finish offers a uniform appearance without coloration that might interfere with future coating processes. Each receiver includes laser-engraved RL556v3 markings for identification and is individually inspected for dimensional consistency before packaging.

The rl556v3 80% ar15 lower – white triggers no background check requirement at the point of sale due to its unfinished state. However, once the user completes the machining process, it becomes a firearm under federal law and must be serialized per ATF guidelines.

Who It’s For

This product is intended for individuals who possess the tooling and technical skill to complete the final machining operations required to finish the lower receiver. The rl556v3 80% ar15 lower – white is appropriate for builders who want to create a custom AR15 lower with specific trigger, grip, and stock configurations. It is not suitable for first-time builders without access to a drill press, end mill, or jig system capable of machining the fire control pocket and safety selector detent channels. Licensed gunsmiths and experienced hobbyists will find the white finish advantageous for projects requiring custom cerakote colors or hydrographic patterns, as the white base provides a clean starting surface.

Shipping & FFL

This item ships directly to your residence or business address. Because the rl556v3 80% ar15 lower – white is not a finished firearm, no Federal Firearms License (FFL) transfer is required at the time of purchase. However, please verify your state and local laws regarding the possession and completion of unfinished receivers. Some jurisdictions impose restrictions on 80% lowers, including serialization requirements and age limits. By purchasing this product, you acknowledge that you are legally permitted to own and complete unfinished firearm components in your jurisdiction. Once the receiver is machined to a functional state, it must comply with all applicable federal and state firearms laws, including serialization and transfer regulations. We recommend consulting with a qualified firearms attorney or your local ATF field office before beginning the completion process.
