Build your next AR-15 platform with precision and control. The RL556V3 80% AR15 Lower in OD Green offers the foundation for a fully customized firearm, designed for the serious builder who demands quality from the ground up. Machined from a 7075-T6 aluminum billet and finished with a durable OD Green anodization, this lower receiver provides the structural integrity and corrosion resistance required for long-term service. As an 80% lower, it allows you to complete the machining process to your specifications, ensuring that your build is truly your own. This component is a direct fit for standard AR-15 upper receivers and mil-spec fire control groups, offering a seamless integration into your existing or new build.

Overview

The RL556V3 80% AR15 Lower in OD Green is a semi-finished receiver that puts the final manufacturing steps in your hands. This part is intended for individuals who wish to complete the machining of the trigger pocket, hammer pin holes, and selector detent channels. The OD Green finish is applied through a Type III Class 2 hardcoat anodizing process, providing a non-reflective surface that resists wear, scratches, and environmental exposure. The RL556V3 designation indicates a specific production run that optimizes the lower for ease of finishing while maintaining tight tolerances. This component is sold as a non-firearm blank and does not require an FFL transfer at the time of purchase.

Features & Specs

Shipping & FFL

This RL556V3 80% AR15 Lower is classified as a non-firearm receiver blank under current ATF guidelines. It may be shipped directly to your residence or business without the involvement of a Federal Firearms License (FFL) dealer.
