If you’re building your own AR-15 from the ground up, the rl556v3 80% ar15 lower – black is a solid foundation that gives you the freedom to finish it exactly how you want. Machined from 7075-T6 aluminum with a hardcoat anodized finish, this 80% lower receiver is ready for your jig, router, and drill press. It’s a straightforward project for anyone comfortable with basic tooling, and the result is a lower that’s every bit as functional as a factory-completed receiver.

Overview

The rl556v3 80% ar15 lower – black is a mil-spec, uncompleted lower receiver. It requires you to remove the remaining material in the fire control pocket, drill the trigger and hammer pin holes, and complete the selector detent channel. Once finished, it accepts standard AR-15 lower parts kits, buffer tubes, and stocks. The black Type III hardcoat anodizing provides lasting corrosion resistance and a low-glare finish that matches most builds.

Features & Specs

• Material: 7075-T6 aluminum – the same alloy used in mil-spec forged receivers, giving you strength and durability without unnecessary weight.
• Finish: Type III Class 2 hardcoat anodized in black – resistant to scratches, oils, and cleaning solvents.
• Compatibility: Accepts all standard AR-15 lower parts kits, pistol grips, buffer tubes, and buttstocks. Designed for use with a dedicated 80% jig and standard router or drill press.

This rl556v3 80% ar15 lower – black includes the rear takedown pin detent hole and bolt catch channel already machined. The trigger pocket is approximately 80% complete, leaving you with a clean, straightforward finishing process. No special tools beyond a quality jig and a steady hand are required.

Who It’s For

This lower is for the home builder who wants to complete a firearm without a serialized receiver purchase. It’s ideal for hobbyists who already own a router and jig, or for someone looking to learn the machining process on a receiver that won’t break the bank. The rl556v3 80% ar15 lower – black also suits builders who want to stockpile receivers for future projects without the serialization paperwork. If you’re comfortable following a drill chart and taking your time with a router, this blank is a rewarding weekend project.

However, once you complete the machining and assemble a functional firearm, you are responsible for complying with all applicable federal, state, and local laws. Some states and municipalities require serialization or background checks for completed 80% receivers. It is your responsibility to know and follow the laws in your jurisdiction before purchasing or finishing this rl556v3 80% ar15 lower – black.

• Ships without any FFL paperwork needed.
• No background check required at time of purchase.
