The Polymer80 G150 AR15 80% Lower Receiver Only represents a critical starting point for builders who demand control over their firearm’s serialization and configuration. This raw, unfinished receiver is precision-molded from high-strength polymer, designed to accept standard AR15 components without the legal designation of a firearm until machining is complete. At a current price accessible for any build budget, this receiver delivers genuine 80% functionality for the informed gunsmith.

Overview
