Overview

The Polymer80 G150 AR15 80% Lower Receiver Only is a precision-molded polymer component designed for AR15 platform builds. As an unfinished lower receiver, it ships without the critical fire control cavity machined, allowing you to complete the work yourself. This receiver is compatible with standard AR15 upper receivers, buffer tubes, and lower parts kits. Its 80% status means it does not require an FFL transfer for purchase, providing a legal and practical starting point for your project. The G150 model features a reinforced polymer design that balances weight savings with durability, making it a popular choice among DIY builders seeking a cost-effective foundation.
