The Aero Precision EPC-9 9mm assembled upper is a complete, ready-to-mount receiver built around a 11" barrel and 9.3" handguard—ideal for builders looking to finish a short, handy 9mm AR platform rifle or pistol without sourcing individual components. This upper ships fully assembled, so you're just a lower receiver, bolt carrier group, and charging handle away from a functional gun. The EPC-9 platform is purpose-built for 9x19 Parabellum, making it a practical choice for home defense, range shooting, or suppressed shooting where 9mm shines.
The heart of the upper is Aero Precision's EPC-9 Enhanced receiver, machined from custom 7075-T6 aluminum and engineered to mil-spec standards. It features a last-round bolt hold open mechanism and standard AR15 takedown and pivot pin lugs, so it plays nice with common lower receivers and parts. The included Enhanced Gen 2 M-LOK handguard uses a one-piece free float design that decouples the barrel from the rail system, supporting accuracy while keeping weight low. Built-in anti-rotation tabs, scalloped rails, and a continuous Picatinny top rail give you multiple mounting options for optics, lights, or other accessories. Quick disconnect sling mounts are positioned at 3, 6, and 9 o'clock.
The 11" chrome moly vanadium barrel is chambered in 9x19 with a 1-in-10 twist and 1/2"x28 threading, finished in QPQ corrosion-resistant coating inside and out. The 1.72" inner diameter of the handguard accommodates most common muzzle devices and 1.5" suppressors, and the design clears low-profile gas blocks. Note: the muzzle device is not pinned or welded, so you'll want to verify fit with your chosen brake or suppressor. This is a solid, no-frills upper for 9mm builds—straightforward, proven Aero quality, and ready to work the moment you bolt it down.
| Caliber | 9x19 Parabellum |
| Barrel Length | 11" |
| Handguard Length | 9.3" |
| Barrel Material | Chrome Moly Vanadium |
| Barrel Finish | QPQ corrosion resistant |
| Barrel Twist | 1 in 10 |
| Muzzle Threading | 1/2"x28 |

| Handguard Rails | M-LOK with continuous Picatinny top rail |
| Sling Mounts | Quick disconnect at 3, 6, 9 o'clock |
| Finish | Black |
| Assembly Status | Fully assembled |
| Compatibility | AR15 lower receivers with standard takedown pins |
You'll need an AR15 lower receiver, a bolt carrier group, a charging handle, and a magazine. The upper itself is completely assembled and ready to attach—just mate it to your lower and you're done with that part of the build.
Yes. The EPC-9 uses standard AR15 takedown and pivot pin lugs, so it's compatible with any standard AR15 lower receiver. Just confirm your lower is chambered or will accept a 9mm magazine—this upper fires 9x19 ammunition.
The handguard's 1.72" inner diameter (1.78" at the barrel nut area) will fit most muzzle devices and 1.5" suppressors. Verify your specific suppressor diameter before purchasing. The muzzle device included is not pinned or welded, so you have flexibility in what you thread on.
Free float design isolates the handguard from the barrel, which means your hand pressure and gear weight don't flex the barrel. This supports more consistent shot placement, especially over longer strings of fire. The M-LOK rail system also gives you more customization options than traditional Picatinny alone.
