RL556V3 80% AR15 Lower – Black

Overview

The RL556V3 80% AR15 lower – black is a precision-machined, unfinished lower receiver designed for builders who want complete control over their firearm project. Manufactured by RL556v3, this 80% lower is constructed from 7075-T6 aluminum and finished in a durable black anodized coating. It is compatible with standard AR15 upper receivers, parts kits, and buffer tube assemblies. As an 80% lower, it requires final machining of the trigger pocket, fire control group hole, and safety selector hole to become a functional receiver. This component is sold as a non-firearm blank under current ATF guidelines and is intended for personal use only.

Who It’s For

This product is intended for experienced firearm builders who own the necessary tools and jigs to complete an 80% lower. It is suitable for hobbyists, custom rifle builders, and anyone who prefers to assemble their own AR15 platform from the ground up. The RL556V3 80% AR15 lower – black is not recommended for first-time builders unless they have prior machining experience or access to a professional shop. It is designed for personal use and should not be transferred or sold after completion without following applicable federal and state laws. If you are looking for a complete, ready-to-fire lower receiver, consider a fully finished stripped lower instead.

• Ideal for DIY builders with router and jig experience
• Suitable for custom project rifles, including pistol or rifle configurations
• Not for those seeking a drop-in, ready-to-assemble lower receiver

Shipping & FFL

Because the RL556V3 80% AR15 lower – black is sold as an unfinished, non-firearm blank, it does not require transfer through a Federal Firearms License (FFL) dealer. It can be shipped directly to your residence in most states. However, some states and localities restrict the purchase, possession, or completion of 80% lowers. It is your responsibility to verify your local laws before ordering. By purchasing this item, you confirm that you are legally permitted to own and complete an 80% lower receiver in your jurisdiction. Once machined, the completed receiver is considered a firearm and must be serialized if sold or transferred. We recommend consulting with a legal professional regarding your specific obligations.

• No FFL transfer required for the unfinished blank
