RL556V3 80% AR15 Lower – White

If you are looking for a clean, ready-to-finish foundation for your next custom AR-15 build, the RL556V3 80% AR15 lower in white offers a solid starting point. This lower receiver is machined from 7075-T6 aluminum and requires only a few final milling steps to complete. It is an excellent choice for hobbyists who want a lightweight, corrosion-resistant platform without the full retail paperwork. The bright white anodized finish stands out on the bench and makes it easy to spot small machining marks as you work. Whether you are a first-time builder or a seasoned gunsmith, this lower gives you the flexibility to create a rifle that is truly your own.

Overview

The RL556V3 80% AR15 lower in white is a billet-machined receiver that comes partially finished. It includes all the critical dimensions and features of a standard AR-15 lower, but the trigger pocket, fire control group pin holes, and selector detent channels are left undrilled. You complete these with a simple jig and a drill press or router. The white anodized finish is uniform and durable, providing a base that accepts paint or cerakote easily if you want to change the color later. This lower is compatible with mil-spec upper receivers and parts kits, so you can build a rifle that runs reliably from the first round.

Features & Specs

• Material: 7075-T6 aluminum with a hardcoat anodized white finish for strength and corrosion resistance.
• Compatibility: Accepts all standard AR-15 lower parts kits, buffer tubes, and stocks. Works with mil-spec uppers.
• Machining: 80% complete – requires drilling of trigger pin holes, selector pocket, and safety detent recess. No serial number required.

This RL556V3 80% AR15 lower – white receiver is machined to tight tolerances. The trigger guard is integral, and the flared magazine well allows for faster reloads. The lower also features a threaded bolt catch pin for easy installation without staking. You will appreciate the crisp, clean lines and the lack of sharp edges on the grip tang.

Who It’s For

This lower is designed for the DIY builder who values control over every part of their rifle. If you have experience with basic metalworking or have used an 80% jig before, the RL556V3 white lower is a straightforward project. It is also a great option for anyone who wants to avoid a paper trail while building a functional AR-15 for range use, hunting, or general target shooting. The white anodized finish is especially popular among builders who plan to cerakote or hydro-dip their lower later, as it provides a bright, even base coat. Whether you are building a lightweight carbine, a precision rifle, or a dedicated .22LR plinker, this lower gives you the freedom to tailor the build to your exact needs.

Shipping & FFL

Because the RL556v3 80% AR15 lower – white is not considered a firearm under federal law (it is less than 80% complete), it can be shipped directly to your home or business without an FFL transfer. No background check is required at the time of purchase. However, once you complete the machining and turn it into a functional receiver, it becomes a firearm and must comply with all applicable federal, state, and local laws. We recommend checking your local regulations before ordering. Some states restrict the possession or completion of 80% receivers, and it is your responsibility to ensure compliance. This product is sold as a raw forging and is intended for personal use only.
