Description

RL556V3 80% AR15 Lower – White

Overview

If you are looking to build a custom AR-15 from the ground up, the RL556V3 80% AR15 lower – white is a solid starting point. This un-machined lower receiver gives you the freedom to complete the firearm at your own pace, on your own terms. The white finish offers a clean, neutral base that works well for cerakote projects or as a unique stand-alone look. Whether you are a first-time builder or a seasoned hobbyist, having a reliable 80% lower is key to a successful build—and the RL556v3 delivers exactly that.

Features & Specs

This RL556V3 80% AR15 lower – white is precision-machined from billet 6061 aluminum, designed to meet mil-spec dimensions while leaving the critical fire control pocket and trigger areas unfinished. The white anodized coating provides a durable, corrosion-resistant surface that is ready for engraving or painting. Each lower is fully compatible with standard AR-15 upper receivers, parts kits, and buffer tubes.

  • Manufactured from 6061-T6 aluminum billet for strength and weight balance
  • White anodized finish for a clean, uniform look
  • Pre-drilled pivot pin and takedown pin holes; 80% completion means no serial number required until finalized

Who It’s For

The RL556V3 80% AR15 lower – white is ideal for DIY builders who want maximum control over their firearm’s final configuration. It suits both hobbyists working on a dedicated project and those looking to learn the machining process for the first time. Because it is an 80% lower, it does not require an FFL transfer at purchase—you can order it directly to your door. However, check your local laws before ordering: some states and municipalities have restrictions on unfinished receivers. This lower is also a popular choice for custom cerakote jobs, as the white base makes color applications pop.

  • Perfect for first-time AR-15 builders wanting a clean, unmarked lower
  • Great for experienced machinists who want to customize the trigger pocket and safety selector
  • Works with standard AR-15 parts kits and jigs for a straightforward build process

Shipping & FFL

Because this is an 80% lower, it is not considered a firearm by federal regulation, so no FFL transfer is required for shipment within the United States. However, you are responsible for knowing and following all applicable laws in your state, county, and city. Some states now require serialization or registration of unfinished receivers. We recommend checking with local authorities before purchasing. We ship discreetly and securely—no signature required for most deliveries, but we cannot ship to P.O. boxes. If you have questions about compatibility or build requirements, reach out to our team.

  • No FFL needed for purchase or shipment—ships directly to your address
  • Buyer must comply with all local, state, and federal laws regarding 80% receivers
  • All sales are final on unfinished items; no returns on machined or modified lowers
