RL556V3 80% AR15 Lower – White

If you are building an AR-15 from the ground up and want a clean, blank canvas that keeps the process straightforward, the rl556v3 80% ar15 lower – white is a solid place to start. This stripped lower receiver is machined from a single block of billet 7075-T6 aluminum, giving you the strength and rigidity you need for a reliable build. The white anodized finish is not just for looks—it provides a consistent surface for custom cerakote or hydrographic work down the road. Whether you are a first-time builder or an experienced tinkerer, this lower is designed to fit standard AR-15 mil-spec parts without guesswork.

Overview

The rl556v3 80% ar15 lower – white is a precision-machined 80% receiver that requires final milling of the fire control pocket and trigger pin holes before assembly. It is made by RL556v3, a brand that focuses on clean, repeatable machining for the home builder. The white finish is a durable Type III hard anodize, which resists scratches and corrosion better than many painted options. This lower gives you the freedom to choose your own trigger, grip, and stock while maintaining a lightweight profile that balances well with most uppers. It ships as a raw forging, so you will need a jig and basic shop tools to complete it.

Features & Specs

This lower is built around a few key details that matter when you are working with an 80% blank. The forging is stress-relieved and heat-treated to T6 spec, meaning it holds up to repeated use without warping. Here are the core specs you should know:

• Material: 7075-T6 aluminum billet, hard anodized white
• Compatibility: Accepts all standard AR-15 lower parts kits and mil-spec buffer tubes
• Pocket depth: Pre-machined to 80% completion, requiring 0.250-inch of material removal for trigger pocket

Beyond the basics, the rl556v3 80% ar15 lower – white has a clean, flat top that makes it easy to fixture in a jig. The bolt catch and safety selector detent holes are pre-drilled and reamed to spec, so you only need to finish the trigger pocket and pin holes. This saves time and reduces the chance of alignment errors during your build.

Who It’s For

This lower is ideal for anyone who wants to complete a firearm without a serialized receiver, or for builders who plan to customize the finish later. It is a good fit for:

• Home gunsmiths who already have a router or drill press and a quality 80% jig
• Shooters looking for a lightweight, non-painted receiver that won’t chip or peel
• Those who want a white base for cerakote or sponge-painting projects

Because the rl556v3 80% ar15 lower – white is an 80% receiver, it requires some mechanical work and attention to detail. If you are comfortable with basic shop tools and following step-by-step instructions, this is a straightforward weekend project. For new builders, we recommend watching a few tutorials and using a quality jig to ensure a clean trigger pocket cut.
