Overview

The Polymer80 G150 is an 80% lower receiver kit designed for the AR-15 platform. It comes as a partially machined receiver that requires final milling and drilling to become a functional firearm component. This kit includes the 80% lower receiver along with a jig and necessary tooling to help you complete the work. The black finish is durable and low-profile, blending well with any upper receiver and handguard setup. Because it is an 80% receiver, it does not have a serial number and is not considered a firearm under federal law until you complete the machining process. This gives you the freedom to build a rifle that is uniquely yours, without the typical paperwork associated with a fully finished lower.

The P80 G150 AR-15 80% Receiver Kit – Black is compatible with standard AR-15 parts, so you can use your preferred trigger, grip, and stock. The included jig is precision-molded to guide your drill and router, reducing the chance of errors during the build process.

Shipping & FFL

No background check is required for the kit itself. However, please be aware of your local and state laws before purchasing. Some states and municipalities have restrictions on 80% receivers, and it is your responsibility to ensure compliance with all applicable regulations. Once you complete the machining and assembly, you may be required to serialize the receiver or register it depending on where you live. Always check your local laws before beginning the build process.
