A .308 polymer lower receiver is a lightweight, durable lower receiver made from high-strength polymer, designed for AR-10 rifles chambered in .308 Winchester or 7.62×51 NATO. It serves as the foundation for the fire control group, magazine well, and buffer system. The .308 polymer lower receiver works with AR-10 upper receivers, lower parts kits, buffer tubes, stocks, magazines, and other standard AR-10 components. It’s ideal for shooters seeking a cost-effective, corrosion-resistant, and easy-to-handle option for custom AR-10 builds.
