The Aero Precision EPC-9 threaded upper receiver with LRBHO is built for shooters stepping up their AR9 pistol caliber rifle build. This precision-machined upper accepts most standard AR15-compatible barrel nuts and handguards, making it a drop-in fit for existing platforms while adding serious capability. The integrated last round bolt hold open (LRBHO) mechanism gives you tactical feedback when rounds run dry—a feature that separates a refined PCC from a basic one. Finished in Kodiak Brown, it looks as good as it performs on the range or in the field.
Aero Precision machined the EPC-9 from custom forged 7075-T6 aluminum, a material choice that guarantees durability under sustained fire. The threaded barrel design lets you add a suppressor, muzzle brake, or flash hider to tune your rifle exactly how you want it. A dimple above the threads ensures proper handguard timing—Aero's attention to detail means no guesswork during assembly. Laser-enged T-marks help you align your upper and handguard quickly and accurately every time.
The EPC-9 follows the standard AR15 takedown and pivot pin lug pattern, so you can pair it with any compatible lower receiver. The LRBHO assembly comes pre-installed and ready to go—just note that it's designed to work with Glock-pattern magazines, the de facto standard for 9mm pistol caliber builds. If you're building a dedicated 9mm AR or upgrading an existing platform, this upper gives you the kind of fit, finish, and function that justifies the investment.
