This unmarked receiver gives you the freedom to finish the build your way, without the need for a serial number or FFL transfer at purchase. Whether you are a first-time builder or a seasoned tinkerer, this lower offers a clean slate with a crisp white finish that stands out from the usual black or gray builds.

Overview

The RL556v3 80% AR15 lower – white is a partially machined receiver that requires final milling of the trigger pocket and fire control group area. It is made from 7075-T6 aluminum, which is the industry standard for AR lowers because it balances strength with weight. The white anodized finish is not just for looks; it resists scratching and corrosion better than many painted finishes. This lower is compatible with all mil-spec AR15 upper receivers and parts kits, so you can pair it with your preferred barrel, stock, and handguard. Because it is an 80% lower, it ships directly to your door without the need for a background check or FFL transfer at the time of purchase.

Features & Specs

• Material: 7075-T6 aluminum forging – the same material used in military-spec lowers
• Finish: White anodized coating for durability and a unique look
• Compatibility: Accepts all mil-spec AR15 upper receivers, lower parts kits, and buffer tubes

This RL556v3 80% AR15 lower – white is pre-drilled for the trigger and hammer pin holes, but the trigger pocket and fire control group well require final machining. You will need a jig and router or drill press to complete the cut. The lower also includes the rear takedown pin detent hole and the bolt catch recess already machined, which saves you some work. The white finish is uniform with no visible tool marks, and the anodizing is sealed to prevent fading over time.

• Pre-machined features: Trigger/hammer pin holes, rear detent hole, bolt catch pocket
• Requires finishing: Trigger pocket, fire control group well, selector detent channel
• Weight: Approximately 0.8 pounds before finishing – light enough for a lightweight build

Who It Is For

This RL556v3 80% AR15 lower – white is ideal for the home gunsmith who wants to learn the machining process without the complexity of a full raw forging. It is also a great choice for builders who want a distinct white receiver for a themed build, such as a winter or snow camouflage rifle. Because it requires no FFL transfer to purchase, it is a straightforward option for those in states where 80% lowers are legal. We recommend this lower for anyone with basic tool experience and a willingness to follow a jig guide carefully. It is not for those who want a drop-in, ready-to-assemble receiver, but if you enjoy the hands-on process, this is a rewarding project.
