RL556V3 80% AR15 Lower – OD Green

The RL556V3 80% AR15 Lower in OD Green represents a precision-engineered foundation for custom AR-15 builds. Machined from a single block of billet 7075-T6 aluminum, this lower receiver is designed for the builder who demands exacting tolerances and durable construction. The OD Green cerakote finish provides corrosion resistance and a low-visibility profile suitable for field applications. As an 80% lower, it requires final machining of the fire control pocket and trigger pin holes to complete the receiver, offering a path to a fully personalized firearm without serialization requirements at the time of purchase. This component is a direct fit for standard AR-15 upper receivers and compatible with mil-spec parts kits.

Overview

The RL556V3 80% AR15 Lower – OD Green is a billet-machined 80% receiver from RL556V3, a manufacturer known for consistent quality in the firearms components sector. This lower is categorized as a parts item and is not a finished firearm. It is sold as an unfinished piece of metal requiring drilling and milling to function as a receiver. The OD Green finish is applied through a Type III hard coat anodizing base layer with a cerakote topcoat, ensuring the color remains stable under heavy use. The design incorporates a flared magazine well for faster reloads and a textured trigger guard area for improved grip. All critical dimensions are held to mil-spec tolerances, within +/- 0.001 inches for pin holes and pocket depths.

Features & Specs

The RL556V3 80% AR15 Lower – OD Green is built around specific engineering choices that prioritize strength and ease of finishing. The billet construction eliminates casting imperfections, and the 7075-T6 aluminum is heat-treated to T6 condition for maximum tensile strength. The OD Green finish is applied in a controlled environment, with a thickness of 1.5 to 2.5 mils. Below are the primary feature sets.

• Material and Construction: 7075-T6 aluminum billet, heat treated to T6, with a Type III hard coat anodized base and OD Green cerakote finish. Weight is approximately 0.7 pounds before finishing. The receiver is reinforced at the buffer tube threads with a 7075-T6 insert.
• Machining Specifications: Pre-drilled pilot holes for safety selector and bolt catch. Trigger pocket is 0.800 inches deep requiring final machining to 1.250 inches. Pocket width is 0.375 inches. Pin holes are located at 0.625 inches from center to center. The rear takedown pin lug is reinforced.
• Compatibility and Fit: Accepts all standard AR-15 lower parts kits (LPK) and drop-in triggers. Upper receiver fitment is tight with a 0.002-inch clearance at the rear lug. Uses standard AR-15 buffer tubes, stocks, and pistol grips. The bolt catch channel is pre-cut for ambidextrous bolt catch options.

Who It Is For

The RL556V3 80% AR15 Lower – OD Green is intended for experienced builders and gunsmiths who possess a drill press, milling machine, or router jig with appropriate end mills. This product is not for first-time builders without access to proper tooling and measurement equipment. It suits individuals who want to create a custom AR-15 with specific trigger, grip, and stock configurations without the constraints of a serialized receiver. The OD Green finish is appropriate for users building a rifle for hunting, range use, or tactical applications where a non-reflective color is preferred. This lower is also suitable for those who wish to complete the receiver themselves to avoid FFL transfer fees and maintain a private build record. It is not a drop-in component and requires a minimum of 4 to 8 hours of skilled machining work.

Shipping & FFL

Because the RL556V3 80% AR15 Lower – OD Green is classified as an unfinished receiver and not a firearm, it does not require transfer through a Federal Firearms License (FFL) dealer. Shipment is made directly to your shipping address. However, it is your responsibility to verify that possession of an 80% lower receiver is legal under all applicable federal, state, and local laws. Some states and municipalities have specific restrictions on the purchase, possession, or finishing of 80% receivers. By purchasing this item, you confirm that you are legally allowed to own and machine this component in your jurisdiction. All sales are final on unfinished receivers. No returns are accepted on machined or modified components. This product is sold as a part, not a firearm.
