Aero Precision EPC-9-T Complete Upper Receiver 9mm 16" – AR-15 Lower Compatible

The Aero Precision EPC-9-T (Enhanced Pistol Caliber 9mm Threaded) is a complete upper receiver assembly chambered in 9mm Luger, designed to work with AR-15 lower receivers equipped with a 9mm magazine well conversion. The 16-inch barrel configuration delivers improved velocity and sight radius while maintaining compatibility with standard AR-15 controls and ergonomics. This setup uses Colt-style 9mm magazines or Glock magazine inserts depending on lower configuration.

Constructed from 7075-T6 aluminum with a black anodized finish, the upper includes Aero's proprietary M4E1 threaded upper receiver, 16-inch nitride-treated barrel, free-float handguard, bolt carrier group, and charging handle. The threaded muzzle accepts standard 1/2x36 muzzle devices. Installation requires a 9mm-compatible lower receiver with appropriate magazine well adapter and ejector—this is not a drop-in conversion for standard 5.56 lowers without modification.
