Description

RL556V3 80% AR15 Lower – White

Overview

If you are looking to start a custom build from the ground up, the RL556V3 80% AR15 Lower – White offers a clean canvas with a crisp, durable finish. This 80% lower receiver is machined from billet 7075-T6 aluminum, meaning you get the strength of a forged part with the tighter tolerances of a machined billet. The white anodized coating is consistent across the entire surface, giving your build a distinctive look that stands out from standard black or FDE receivers. Because this is an 80% lower, it requires finishing the fire control cavity and trigger pocket before it becomes a functional firearm component. That gives you the flexibility to complete the work at your own pace, with your own tools.

Features & Specs

The RL556V3 80% AR15 Lower – White is designed for builders who want a reliable foundation without the extra weight or unnecessary bulk. Every pocket, threading, and pin hole is pre-machined to mil-spec dimensions, so your LPK, trigger, and buffer tube will drop in without fitting issues. The white anodized finish is corrosion-resistant and holds up well to handling during the engraving and assembly process.

Who It’s For

The RL556V3 80% AR15 Lower – White is built for the home gunsmith, the weekend tinkerer, and the builder who values a unique aesthetic. If you have experience with a drill press, router jig, or even hand files, this lower gives you the satisfaction of completing a receiver yourself. It is also a solid choice for someone who wants to stockpile raw lowers without the paperwork that comes with a serialized receiver. Because the white finish is consistent and clean, it pairs well with contrasting upper receivers, handguards, and furniture. Whether you are building a lightweight carbine or a precision rifle, this lower provides a strong, reliable starting point.

Shipping & FFL

This RL556V3 80% AR15 Lower – White is not a firearm and does not require an FFL transfer for shipping. It can be shipped directly to your door in most states. However, you must check your local and state laws before ordering. Some states restrict the possession or finishing of 80% receivers, and it is your responsibility to comply with all applicable regulations. For customers who prefer to have the lower sent to an FFL for peace of mind, we can accommodate that upon request. No serial number is required for this product, and no background check is needed at the time of purchase. Build responsibly and follow all local laws regarding the completion and serialization of firearm components.
