The Aero Precision EPC-9 9mm assembled upper receiver with a 16-inch barrel and 15-inch handguard is purpose-built for shooters looking to complete a reliable, modular 9mm AR-pattern build. This is a true complete upper—machined, assembled, and ready to accept your bolt carrier group and charging handle. Whether you're setting up a tack-driving range gun, a practical home-defense build, or an affordable training platform, the EPC-9 platform gives you a solid foundation without the guesswork of sourcing matched components.
The heart of this upper is Aero's Enhanced Gen 2 M-LOK handguard, a free-float design that separates the rail from the barrel for consistent accuracy. The 1-piece construction uses anti-rotation tabs and scalloped rails to keep everything locked down while shaving weight. You get continuous picatinny on top, quick-disconnect sling points at 3, 6, and 9 o'clock, and internal clearance that'll run most common muzzle devices and compact suppressors. The generous diameter and internal diameter specs mean you won't fight mounting accessories or running suppressed.
The 16-inch 9x19 chrome moly vanadium barrel is quartered in 1:10, threaded 1/2x28, and finished with QPQ corrosion resistance both inside and out—a tough, corrosion-resistant coating that handles lead fouling and environmental exposure. The EPC-9 receiver itself is 7075-T6 forged aluminum with the last-round bolt hold-open feature, standard AR15 take-down/pivot pattern, and mil-spec machining. It's compatible with Aero's other Enhanced and Quantum handguards if you ever want to swap setups.
One important note: the included muzzle device is not pinned or welded, and you'll need to source a BCG and charging handle separately. If you're familiar with AR platforms, this upper will bolt straight to your lower receiver and be ready to fire—no fitting, no mystery parts, just honest engineering from a brand that understands what shooters actually need.

| What's Included | EPC-9 Upper Receiver, 16" barrel, 15" Enhanced Gen 2 M-LOK handguard, unfixed muzzle device |
| What's NOT Included | Bolt Carrier Group (BCG), Charging Handle |
| Finish | Black |
The upper is fully assembled and headspaced. You'll need to add a bolt carrier group and charging handle, then attach it to your AR-15 lower receiver. The muzzle device included is not pinned or welded, so you can install it or replace it as needed.
Yes. The EPC-9 uses the standard AR15 take-down and pivot pin lug pattern, so it will fit any mil-spec compatible AR-15 lower receiver.
The handguard is designed to accommodate 1.5-inch suppressors, and the internal diameters allow most standard muzzle devices to fit without modification. Your specific suppressor's outside diameter should be verified, but the 1.72-inch and 1.78-inch internal diameters provide generous clearance for typical configurations.
The EPC-9 Enhanced Upper Receiver is compatible with Aero Precision's AR15 Enhanced and Quantum handguards, giving you flexibility to reconfigure your build down the road.
