RL556V3 80% AR15 Lower – OD Green

If you are looking to build a truly custom AR-15 from the ground up, the RL556V3 80% AR15 lower in OD Green is a solid foundation that gives you the control you deserve. This 80% lower receiver is machined from a single block of billet aluminum, leaving the critical fire control pocket and trigger housing unfinished, so you can complete the machining at home. The OD Green anodized finish is durable and low-glare, making it an excellent choice for both range builds and practical field rifles. Whether you are a first-time builder or a seasoned gunsmith, this lower offers the precision and rigidity you need without the paperwork of a fully serialized receiver.

Overview

The RL556V3 is a direct continuation of the reliable RL556 platform, refined for easier machining and improved ergonomics. This 80% lower is designed to be compatible with standard mil-spec AR-15 parts kits, so you can pair it with your preferred trigger, grip, and stock. The OD Green color is applied using a hardcoat anodizing process that resists scratches and corrosion, keeping your build looking fresh through heavy use. Because it is an 80% receiver, it requires final machining of the fire control pocket, trigger pin holes, and selector detent channel before assembly. This gives you the satisfaction of building a firearm from a blank slate, while keeping the process straightforward for anyone with basic tools and a jig.

Features & Specs

• Machined from 7075-T6 billet aluminum for high strength and light weight; Type III hardcoat anodized in OD Green for lasting durability.
• Designed to accept standard AR-15 lower parts kits, including mil-spec triggers, grips, and buffer tubes. Compatible with nearly all aftermarket uppers.
• Pre-machined trigger guard and integrated flared magazine well for easier reloads and faster manipulation under stress.

The RL556V3 also features a threaded rear takedown pin detent hole, a reinforced bolt catch area, and a crisp, deep engraving for the RL556V3 logo. The overall weight is approximately 6.9 ounces, making it one of the lighter 80% lowers on the market without sacrificing rigidity. Specs include a standard .250-inch trigger pin diameter and a .154-inch hammer pin diameter, matching mil-spec dimensions exactly.

Who It’s For

This RL556V3 80% AR15 lower in OD Green is for the hands-on enthusiast who wants to build a rifle that fits their exact preferences. It is ideal for hobbyists with a drill press or router jig who enjoy the process of completing a receiver at home. It works well for those assembling a dedicated hunting build, a coyote gun, or a range toy where color matching matters. It is also a great choice for preppers and tinkerers who want to stockpile unfinished receivers for future builds without the serialization requirements. If you are comfortable with basic machining and following a jig template, this lower will reward you with a tight-fitting, reliable platform.

Shipping & FFL

Because the RL556V3 is an 80% lower receiver and does not meet the definition of a firearm under federal law, it can be shipped directly to your home address without a background check or FFL transfer. No special licensing is needed to purchase or receive this product. However, once you machine the fire control pocket and complete the receiver, it becomes a firearm and must be treated as such under all applicable local, state, and federal laws. We recommend checking your state and local regulations regarding the manufacture of firearms at home before beginning your build. By purchasing this product, you acknowledge that you are legally allowed to possess and complete an 80% receiver in your jurisdiction.
