First Impressions of Aero Precision EPC MOE Lower Parts Kit Minus FCG
The Aero Precision EPC MOE Lower Parts Kit Minus FCG is designed for AR-9 builds utilizing Aero Precision‘s Enhanced Pistol Caliber (EPC) lower receiver. This kit offers a curated selection of high-quality components, streamlining the building process. It’s missing only the fire control group (FCG), allowing builders to select their preferred trigger.
I’ve been building AR platforms for over a decade, primarily focusing on AR-15s. However, the rising popularity of pistol caliber carbines (PCCs) intrigued me, leading me to explore the AR-9 platform. My goal was a reliable and accurate home defense weapon.
Upon unboxing, the individual components were neatly organized. The Magpul MOE grip immediately stood out with its familiar and comfortable texture. The parts exuded a high-quality feel, consistent with Aero Precision‘s reputation.
I considered the CMMG Lower Parts Kit and the PSA AR-9 Lower Build Kit. I chose the Aero Precision EPC MOE Lower Parts Kit Minus FCG primarily for its compatibility with my Aero Precision EPC lower receiver. It also allows me to choose my own trigger group, a feature that matters to me.
My first impression was positive; I was excited about the prospect of a straightforward and reliable build. The quality of the components instilled confidence. It was a solid foundation for a PCC build.
Real-World Testing: Putting Aero Precision EPC MOE Lower Parts Kit Minus FCG to the Test
First Use Experience
The initial testing took place at my local indoor shooting range. I paired the lower receiver, assembled with the Aero Precision EPC MOE Lower Parts Kit Minus FCG, with a 9mm upper receiver. I used a variety of ammunition, including 115 grain FMJ and 124 grain JHP.
The Magpul MOE grip provided a solid and comfortable hold, even during rapid fire. No parts exhibited any immediate failures. All small parts functioned as they should during the assembly process.
Assembly was straightforward and intuitive. The only tool I required besides basic punches and roll pin holders was the included 4-40 set screw. I was able to assemble my lower receiver in a very timely manner.
Extended Use & Reliability
After several range trips and hundreds of rounds, the Aero Precision EPC MOE Lower Parts Kit Minus FCG has proven incredibly reliable. There are no signs of significant wear on any of the components. The finish on the metal parts remains intact.
Maintenance is minimal. A quick wipe-down and occasional lubrication of the moving parts are all that’s needed. This kit has continued to work as expected.
Compared to previous lower parts kits I’ve used, the Aero Precision kit stands out for its quality and precise fit. Other kits sometimes require minor adjustments or replacements of individual parts. This was not necessary with the Aero Precision kit.
