Overview

The RL556v3 80% lower receiver is a precision-machined 7075-T6 aluminum blank that requires final machining to become a functional receiver. It ships as a non-firearm, meaning no serial number and no FFL transfer for the blank itself, though you will need to complete the machining steps before assembly. The Flat Dark Earth anodized finish is applied evenly across the entire lower, providing corrosion resistance and a consistent matte look that matches common rifle furniture. This is the same material and finish used by major manufacturers, so you are getting a part that holds up to repeated use and cleaning without fading or chipping prematurely.

Features & Specs

The rl556v3 80% ar15 lower – flat dark earth is designed to work with common finishing jigs and router setups.

Every spec point here supports a build that feels solid and runs reliably.

It also works well for those who want to keep a spare lower on hand for future builds, as the RL556v3 is a proven design that accepts nearly all aftermarket parts. Whether you are building a lightweight carbine or a precision rifle, the RL556v3 80% AR15 lower in Flat Dark Earth gives you the flexibility to tailor the final product to your exact needs.
