The Aero Precision EPC Uppers are designed specifically for pistol-caliber carbines (PCCs) and pistols, providing a versatile and reliable platform for builders who prefer customizability and precision. The lineup includes EPC Stripped Uppers, EPC Assembled Uppers, and EPC Complete Uppers, catering to a wide range of preferences and build requirements. EPC uppers are optimized for blowback operation, a common system for PCCs, ensuring dependable cycling in calibers like 9mm and .40 S&W. All Aero Precision EPC Uppers are machined from 7075-T6 aluminum for strength and durability. They feature a sleek design with a Type III hardcoat anodized finish for corrosion resistance. The stripped and assembled models provide flexibility for customization, while the complete uppers come fully assembled with the barrel, handguard, and other components, ready to pair with an EPC lower receiver. Each upper includes a Picatinny top rail for optics mounting, and the absence of a forward assist keeps the design lightweight and streamlined. Compatible with Glock-pattern magazines and Aero Precision EPC-9 lowers, these uppers are ideal for builders looking to create a high-performance pistol-caliber firearm.
