Overview

The RL556v3 80% AR15 lower – Flat Dark Earth is a raw, unfinished lower receiver that requires final machining before it can be used as a functional firearm component. As an 80% lower, it is not considered a firearm by the ATF, meaning it can be shipped directly to your doorstep without an FFL transfer. The Flat Dark Earth finish provides a durable, non-reflective surface that integrates well with modern rifle builds. This part is manufactured to tight tolerances, ensuring compatibility with standard AR-15 upper receivers and parts kits.
