P80 G150 AR-15 80% Receiver Kit – Black

The p80 g150 ar-15 80% receiver kit – black from Polymer80 represents a precision-engineered platform for the dedicated builder. Designed for users who require full control over their firearm’s assembly and legal configuration, this kit provides the foundational components necessary to complete a custom AR-15 pattern rifle or pistol. The kit is centered around an 80% lower receiver, meaning the critical fire control cavity is unfinished and requires the end user to perform material removal to achieve a functional state. This approach allows the builder to avoid serialization requirements, as the part is not yet a firearm under federal regulation. Every component in this black-finished kit is manufactured to tight tolerances, ensuring compatibility with standard AR-15 upper receivers and parts kits.

Overview

This build kit is specifically configured for the AR-15 platform and includes the patented Polymer80 G150 80% lower receiver, which features a reinforced polymer construction with integral steel trigger pin inserts for extended durability. The kit also contains all necessary jigs, drill bits, and end mill tooling required to complete the receiver pocket. The black anodized finish provides corrosion resistance and a uniform appearance. The p80 g150 ar-15 80% receiver kit – black is designed to work with mil-spec AR-15 components, allowing the builder to select their preferred trigger group, stock, grip, and upper assembly. Polymer80 has engineered this kit to reduce build complexity while maintaining structural integrity at the critical buffer tube and receiver extension interface.

Who It’s For

This kit is intended for the experienced hobbyist or first-time builder who possesses basic mechanical skills and access to standard shop tools. The p80 g150 ar-15 80% receiver kit – black is ideal for individuals who wish to construct a firearm without serialization, or for those who want to learn the mechanical principles of AR-15 lower receiver finishing. It is suitable for builders planning to install premium trigger systems or custom upper assemblies, as the completed lower accepts all mil-spec components. This product is not for casual shooters seeking a complete, ready-to-fire rifle; it requires dedicated time, attention to detail, and proper tooling. The kit is also appropriate for gunsmiths who prefer to maintain a stock of unfinished receivers for custom builds.

Shipping & FFL

Because the lower receiver is an 80% blank and does not meet the definition of a firearm under the Gun Control Act, this product can be shipped directly to your residence or business address without the involvement of a Federal Firearms License (FFL) dealer. No background check is required at the time of purchase. However, once you complete the receiver by machining the fire control pocket, the part becomes a firearm under federal law and must be serialized if you intend to transfer it. Polymer80 provides no warranty or support for modifications made outside of the provided instructions. It is your responsibility to verify compliance with all local, state, and federal laws regarding the possession and completion of unserialized firearm components. We recommend consulting with a legal professional before beginning assembly. The p80 g150 ar-15 80% receiver kit – black ships in a discreet, plain package via UPS or FedEx Ground with adult signature required upon delivery.
