P80 G150 AR-15 80% Receiver Kit – Black

The P80 G150 AR-15 80% Receiver Kit – Black offers a precise and methodical approach to building a custom AR-15 platform from the ground up. Manufactured by Polymer80, a recognized name in the firearms components industry, this kit provides the essential blank receiver and associated jig components required for a home-based build. Designed for the knowledgeable enthusiast, this kit requires drilling and finishing of the 80% lower receiver before assembly.

Overview

The P80 G150 AR-15 80% Receiver Kit – Black is a comprehensive package that includes an unfinished, black anodized 7075-T6 aluminum lower receiver and a dedicated multi-platform jig system. As an 80% receiver, the critical fire control cavity and pin holes are not machined, meaning the builder must complete these operations themselves. This kit is intended for individuals who possess the necessary tools, knowledge, and patience to finish a receiver to specification. The kit does not include a completed firearm and is not a ready-to-assemble lower. It is a blank canvas for the experienced builder.

Who It’s For

The P80 G150 AR-15 80% Receiver Kit – Black is intended for the experienced builder who understands the mechanical tolerances of the AR-15 platform. This product is not for first-time firearm assemblers. It is designed for individuals who are proficient with drill presses, end mills, and measurement tools, and who wish to complete a receiver from an 80% state. This kit is appropriate for those who want to control the exact specifications of their lower receiver without purchasing a fully completed unit. It is not suitable for those seeking a pre-assembled firearm or for those without access to a workshop environment with appropriate tooling.

• Recommended for builders with prior experience in finishing 80% receivers or similar metalworking projects.
• Not recommended for individuals who do not own or have access to a drill press or a stable clamping system.
• Ideal for those who wish to build a single AR-15 lower receiver using a repeatable jig system.
