P80 G150 AR-15 80% Receiver Kit – OD Green

For builders who demand precision without the paperwork, the P80 G150 AR-15 80% Receiver Kit in OD Green delivers a streamlined foundation for a custom rifle. This kit is built around the G150 jig system, which provides a repeatable, rigid platform for completing your lower receiver at home. The OD Green finish offers low-visibility utility for field use or tactical builds, while the 80% design keeps your project off the books until you choose to serialize it. Whether you are starting from scratch or replacing a worn lower, this kit holds to the tight tolerances that Polymer80 is known for in the industry.

Overview

The P80 G150 AR-15 80% Receiver Kit – OD Green is a complete solution for the home builder who wants to finish a lower receiver without specialized tooling beyond a standard drill press or router. The kit includes the unfinished 80% lower, the proprietary G150 jig, drill bits, end mill, and all necessary hardware. The OD Green color is applied during the molding process, not as a surface coating, so it resists chipping and wear through repeated handling. This kit eliminates guesswork by providing indexed alignment points that match the jig to the receiver, ensuring your trigger group and buffer tube sit correctly on the first pass.

Features & Specs

• Includes: 80% lower receiver, G150 multi-platform jig, hardened steel drill bits, carbide end mill, trigger guard, and all springs/pins
• Material: Forged 7075-T6 aluminum with OD Green anodized finish for corrosion resistance and durability

Manufactured by Polymer80, this kit is designed for use with a standard drill press or router. The G150 jig clamps to the receiver using four contact points to prevent shifting during machining. The included end mill cuts the trigger pocket and safety selector hole in one pass, while the drill bits are sized for the buffer tube threads and bolt catch pin. The lower receiver is fully compatible with .223 Remington, 5.56 NATO, and .300 Blackout uppers.

• Included tools: 1/8 inch drill bit, 5/32 inch drill bit, 3/8 inch end mill, alignment pins, and jig hardware
• Compliance: 80% lower requires machining to become a functional firearm receiver; no serial number, no FFL transfer required for purchase

Who It’s For

The P80 G150 AR-15 80% Receiver Kit – OD Green is intended for experienced firearm builders who have access to a drill press or router and understand the legal requirements for completing an unfinished receiver. This kit suits the shooter who wants to build a dedicated hunting rifle with a low-profile color, a defensive carbine for mixed terrain, or a spare lower for a future upper build. It is also a good choice for the builder who prefers to keep their lower off the registry until they decide to engrave it. If you have completed a Polymer80 pistol frame or an AR-15 lower before, the G150 jig system will feel familiar, with the same attention to alignment and repeatability.

• Builders with basic machining experience and a drill press or router
• Shooters who want an OD Green finish for woodland, desert, or all-purpose use
• Anyone who wants to retain full control over their lower receiver documentation and serialization

Shipping & FFL

This P80 G150 AR-15 80% Receiver Kit – OD Green ships directly to your door with no FFL transfer required because the receiver is not yet a firearm. It is classified as an unfinished receiver blank under ATF guidelines. However, once you complete the machining, you must comply with all federal, state, and local laws regarding serialization, ownership, and transfer. It is your responsibility to verify that finishing an 80% receiver is legal in your jurisdiction before purchasing. We ship via UPS Ground to all 48 contiguous states. International shipping is not available. No signature is required for delivery, but we recommend using a secure address. If you choose to sell or transfer the completed receiver in the future, it must go through a Federal Firearms License holder. We do not provide legal advice; consult an attorney if you have questions about your build.
