Overview

The rl556v3 80% ar15 lower – flat dark earth is a pre-machined billet 80% lower receiver designed for home finishing. It is constructed from 7075-T6 aluminum for strength and weight balance, then given a Type III hard coat anodized finish in Flat Dark Earth. This lower is compatible with standard AR-15 upper receivers, buffer tubes, and trigger groups, making it a versatile choice for both first-time builders and experienced gunsmiths. As an 80% lower, it requires final machining of the fire control pocket and trigger pin holes before it can be completed into a functional firearm.

Who It’s For

This rl556v3 80% ar15 lower – flat dark earth is intended for individuals who wish to complete their own firearm at home using standard tooling (drill press, jig, and end mill). It is ideal for builders who want a durable, cosmetic finish without the wait or cost of a serialized receiver. The Flat Dark Earth color suits tactical builds, desert or woodland camo patterns, or matching existing FDE furniture. This product is not for those seeking a ready-to-assemble lower; it requires mechanical skill and appropriate safety equipment to complete.
