First Impressions of Aero Precision EPC-9 16in 9mm Threaded Complete Upper Receiver with Flash Hider
The Aero Precision EPC-9 16in 9mm Threaded Complete Upper Receiver with Flash Hider represents a compelling option for those seeking to build a reliable and accurate pistol-caliber carbine (PCC). Aero Precision has established a solid reputation for quality AR-platform components, and this upper receiver aims to extend that reputation into the increasingly popular 9mm PCC market. With its 16-inch barrel, free-float handguard, and compatibility with Glock magazines (via a dedicated lower receiver), this upper promises both accuracy and versatility.
My journey to this upper started with a desire to build a dedicated PCC for both recreational shooting and potential home defense. I wanted a platform that was accurate, easy to shoot, and chambered in an affordable caliber. The Aero Precision EPC-9 platform quickly rose to the top of my list.
The Aero Precision EPC-9 upper arrived well-packaged. The first thing I noticed was the solid feel and clean lines of the receiver. The finish was even and the handguard felt secure. The included A2 flash hider was a familiar and functional touch.
I considered a few other options before settling on the Aero Precision offering. I looked at complete uppers from Palmetto State Armory and Faxon Firearms. I ultimately chose the Aero Precision due to its reputation for quality control and the sleek design of their ATLAS R-ONE handguard.
My initial reaction was positive. I was eager to pair it with a lower and get it to the range. The fit and finish exceeded my expectations, and I felt confident that it would perform well.
Real-World Testing: Putting Aero Precision EPC-9 16in 9mm Threaded Complete Upper Receiver with Flash Hider to the Test
First Use Experience
My initial testing took place at an indoor shooting range. I paired the Aero Precision EPC-9 upper with an Aero Precision EPC-9 lower receiver and used Glock 17 magazines loaded with 115 grain FMJ ammunition. The upper ran flawlessly out of the box.
I put approximately 200 rounds through the upper during the first session. There were no failures to feed, fire, or eject. The recoil impulse was manageable, and the rifle felt well-balanced.
The Aero Precision EPC-9 proved to be surprisingly accurate. I was able to achieve tight groupings at 25 yards with minimal effort. The 16-inch barrel clearly provided a noticeable increase in velocity and accuracy compared to shorter pistol-length 9mm platforms.
Extended Use & Reliability
After several months of use and approximately 1000 rounds fired, the Aero Precision EPC-9 upper has proven to be exceptionally reliable. I have used a variety of ammunition, including 115 grain FMJ, 124 grain FMJ, and 147 grain hollow points, all without any issues. It handles everything I feed it.
There are minimal signs of wear and tear. The finish has held up well, and all components remain tight and secure. The ATLAS R-ONE handguard shows no signs of loosening or shifting, even after repeated use and handling.
Cleaning and maintenance are straightforward. The upper disassembles easily for cleaning, and all parts are readily accessible. A standard AR-15 cleaning kit is sufficient for maintaining the EPC-9 upper.
Compared to previous experiences with other 9mm AR platforms, the Aero Precision EPC-9 stands out for its reliability and accuracy. I’ve experienced fewer malfunctions and tighter groupings with this upper than with other comparable options. The quality speaks for itself.
