Let’s Dive into Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider
The Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider is a long-range precision powerhouse, built for the AR-10 platform. Manufactured by Aero Precision, a company renowned for quality and precision, this complete upper receiver promises exceptional accuracy and reliability in the popular 6.5 Creedmoor caliber. This upper is available in Black and Flat Dark Earth. With its 20-inch barrel, M-LOK handguard, and A2 flash hider, this complete upper receiver offers a compelling blend of features for both seasoned shooters and those looking to step into the world of long-range AR platforms.
My pursuit of this particular upper receiver stemmed from a desire to build a dedicated long-range AR-10. I needed a reliable and accurate upper that could consistently deliver sub-MOA performance without requiring extensive aftermarket modifications. The promise of Aero Precision’s quality and the 6.5 Creedmoor’s inherent long-range capabilities made it a natural choice.
Upon unboxing, I was immediately impressed with the fit and finish. The Aero Precision upper receiver felt solid and well-made, with a clean, even coating of anodizing. The weight felt appropriate for a 20-inch heavy barrel, suggesting a robust construction capable of withstanding the rigors of extended range sessions.
Compared to other complete uppers I considered, such as those from Brownells or Palmetto State Armory, the Aero Precision stood out due to its reputation for precision machining and attention to detail. While those other options offered more budget-friendly alternatives, the Aero Precision’s promise of consistent accuracy and premium components justified the higher price point. I also preferred the M5E1 enhanced upper receiver that eliminates the need to align the barrel nut and the handguard.
My first impression was one of excitement mixed with a touch of anticipation. I was eager to get it mounted on my lower and see if it lived up to the hype. I felt a sense of confidence that Aero Precision would deliver on its promise of quality and accuracy.
Real-World Testing: Putting Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider to the Test
First Use Experience
My first outing with the Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider was at my local shooting range, known for its 100-600 yard lanes. I mounted the upper on my Aero Precision M5 lower receiver, paired it with a quality scope, and grabbed a selection of factory 6.5 Creedmoor ammunition from Hornady and Federal. The weather was mild and sunny, providing ideal conditions for testing.
The upper performed flawlessly from the very first shot. I quickly zeroed the scope and began working on group sizes at 100 yards. The rifle exhibited impressive accuracy, consistently producing sub-MOA groups with both Hornady and Federal ammunition. The recoil was manageable thanks to the 6.5 Creedmoor’s relatively mild recoil impulse and the heavy profile barrel.
There were no immediate issues or surprises, just consistent performance and excellent accuracy. The smooth cycling of the bolt carrier group, which I added separately as it does not come with the upper, was also a welcome surprise.
Extended Use & Reliability
After several months of regular use, the Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider has proven to be a reliable and durable performer. I’ve put several hundred rounds through it, and it continues to deliver consistent accuracy. There has not been any degradation in performance.
I have noticed minimal signs of wear and tear. The anodized finish has held up well, even after repeated cleanings. Cleaning and maintenance are straightforward, requiring only basic AR-10 cleaning tools and solvents.
Compared to previous experiences with other AR-10 uppers, the Aero Precision stands out for its consistent accuracy and reliability. Cheaper uppers often exhibit accuracy issues or require extensive tuning to achieve acceptable performance, but the Aero Precision performed exceptionally well right out of the box. It outperforms expectations.
