P80 G150 AR-15 80% Receiver Kit – Black

For the serious builder seeking a foundation that balances precision engineering with hands-on craftsmanship, the P80 G150 AR-15 80% Receiver Kit – Black offers a complete starting point. Manufactured by Polymer80, this kit is categorized under build kits and is designed for individuals who intend to complete a firearm for personal use in compliance with all applicable federal, state, and local laws. This kit provides the core components necessary to begin a custom AR-15 platform build, requiring the end user to perform the final machining and assembly steps on the 80% lower receiver.

Overview

The P80 G150 AR-15 80% Receiver Kit – Black is a comprehensive parts package that streamlines the initial phase of an AR-15 project. The kit includes a black anodized 80% lower receiver, a complete lower parts kit (LPK) with fire control group components, a buffer tube assembly, and a carbine-length buffer spring and buffer. Every component in this kit is sourced to meet the exacting tolerances expected by experienced builders. The 80% lower receiver itself is precision-molded from reinforced polymer, providing a lightweight yet durable foundation. This kit allows the builder to focus on the critical machining of the fire control cavity and trigger pin holes without sourcing individual small parts separately.

Features & Specs

This kit is defined by its specific component set and material specifications. The 80% lower receiver is the centerpiece, requiring the builder to complete the pocket and trigger pin holes using a standard 80% lower jig and router or drill press. The black finish is applied using a durable anodized coating that resists wear and corrosion. The included lower parts kit features standard mil-spec components, including a trigger, hammer, disconnector, selector, bolt catch, and all necessary springs and pins. The buffer tube assembly is constructed from 7075-T6 aluminum and is compatible with standard AR-15 carbine stocks.

Who It’s For

The P80 G150 AR-15 80% Receiver Kit – Black is intended for experienced builders who are comfortable with mechanical assembly and have access to the required machining tools. This kit will suit the hobbyist who wants to complete a lower receiver from a raw 80% state, gaining familiarity with the internal geometry of the AR-15 fire control system. It is also appropriate for the shooter who prefers to build a custom firearm configuration rather than purchasing a completed rifle. This product is not intended for individuals unfamiliar with the legal requirements surrounding 80% receivers or those without the proper jigs and tooling to complete the lower receiver safely. The builder assumes full responsibility for ensuring the completed firearm is legally manufactured and compliant with all laws.
