Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard Review

The Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard Made a Bold First Impression

The Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard arrived on my doorstep, and I was immediately struck by the clean lines and purposeful design. As someone who’s spent over a decade immersed in the world of tactical gear, I’ve seen countless AR-patterned rifles and pistols. This 9mm upper, manufactured by Aero Precision, promised something different: AR ergonomics combined with the affordable and readily available 9mm cartridge.

My journey to acquiring this upper started with a desire for a more economical training platform. I love shooting my AR-15, but the rising cost of ammunition was becoming a real deterrent to frequent range visits. I began looking into pistol caliber carbines (PCCs) as a solution, drawn to the cheaper ammunition and reduced recoil, allowing for longer and more enjoyable training sessions.

Unboxing the Aero Precision EPC-9, I was impressed by the fit and finish. The anodized black finish was flawless, and the handguard felt solid in my hand. The weight felt balanced, and there were no visible blemishes or imperfections.

I considered a few other options, including complete PCC builds from other manufacturers. Ultimately, I chose the Aero Precision EPC-9 upper for its compatibility with my existing AR-15 lower receivers and the reputation of Aero Precision for quality components. The modularity of the AR platform is a huge draw, and this upper allowed me to leverage that without having to purchase a completely new firearm.

My first impression was one of excitement and anticipation. I couldn’t wait to get this upper mounted on one of my lowers and hit the range. The promise of a reliable and accurate 9mm AR, at a reasonable price point, was definitely appealing.

Real-World Testing: Putting Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard to the Test

First Use Experience

My first range trip with the Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard was at my local outdoor shooting range. I paired it with an Aero Precision M4E1 lower receiver that I had previously built, using a standard AR-15 trigger and buffer system. I brought a variety of 9mm ammunition, ranging from 115-grain FMJ to 147-grain hollow points, to test its reliability.

The weather was clear and sunny, but there was a slight breeze. Initial performance was impressive; the EPC-9 cycled flawlessly with all ammunition types I tested. The recoil was significantly less than my .223 AR-15, making it easy to stay on target for rapid follow-up shots.

The EPC-9 was incredibly easy to use right out of the box. The AR-15 controls were familiar, and I didn’t need any time to adjust to the platform. One pleasant surprise was the accuracy; I was consistently hitting steel targets at 50 yards with ease.

Extended Use & Reliability

After several months and hundreds of rounds, the Aero Precision EPC-9 9mm Assembled Upper Threaded 16″ CMV BBL 15″ Handguard continues to perform flawlessly. I’ve used it in various conditions, including a few rainy range days, and haven’t experienced any malfunctions. The finish has held up well, with no noticeable wear or scratches.

Maintenance is straightforward; I clean the barrel and bolt carrier group after each range trip. The QPQ corrosion resistant finish on the barrel has made cleaning particularly easy. Compared to some of my other firearms, the EPC-9 requires minimal effort to keep running smoothly.

The EPC-9 has definitely outperformed my expectations. It’s become my go-to firearm for range training and home defense. Its reliability, accuracy, and low recoil make it a joy to shoot.
