The Aero EPC-9-T 16" 9mm complete upper receiver brings rifle-grade engineering to modern pistol-caliber builds. Aero Precision designed this assembled upper as a plug-and-play solution for 9mm AR platform rifles, delivering the precision and durability you expect from the brand without the guesswork of sourcing and matching individual components. This is the right choice if you're building a 9mm AR from the ground up or upgrading an existing lower receiver—just add a bolt carrier group and charging handle to get running.

The 16-inch 9mm chrome moly vanadium barrel gives you velocity, reliability, and versatility for target shooting, home defense, or recreational plinking. The integrated ATLAS S-ONE handguard keeps weight down while maintaining a slim, clean profile—and Aero's proprietary mounting system gives you real estate for optics, lights, or vertical grips without unnecessary bulk. This is a complete upper receiver, fully assembled and ready to attach to a compatible lower.

Build quality is solid throughout. Every component is designed and manufactured to Aero's standards, so you don't have to second-guess fitment or reliability. The upper arrives assembled, which saves time and eliminates assembly headaches for builders of any skill level. Whether you're a first-time 9mm AR builder or adding to an existing collection, this complete upper takes the complexity out of the process.
