The Aero Precision EPC-9 Complete Lower Receiver is a fully assembled lower receiver designed for pistol-caliber carbines (PCCs) chambered in 9mm or similar calibers. As a complete lower, it includes all necessary components such as the lower receiver, trigger assembly, safety selector, magazine release, buffer system, and stock. Pre-assembled and ready to pair with a compatible EPC-9 upper receiver, it provides a convenient and reliable foundation for building a PCC. Built from high-quality 7075-T6 aluminum, the EPC-9 Complete Lower is precision-machined for durability and compatibility with Glock-pattern magazines. It features an integrated trigger guard and a flared magazine well for faster reloads. Typically equipped with Magpul MOE SL furniture for ergonomic handling, the lower includes a Mil-Spec trigger for consistent performance and a proprietary buffer system optimized for blowback operation. Finished with Type III hard anodizing for corrosion resistance, this complete lower is ideal for shooters looking to build a high-quality and dependable PCC.
