First Impressions of Aero Precision M4E1-T 16in .350 Legend Complete Upper with Flash Hider
The Aero Precision M4E1-T 16in .350 Legend Complete Upper with Flash Hider promises to bring modern AR-15 ergonomics and precision to the .350 Legend cartridge, a round increasingly popular for hunting in states with straight-walled cartridge restrictions. The Aero Precision name carries weight, known for quality AR components, so expectations were high. This complete upper offers a compelling option for hunters and recreational shooters looking to explore the .350 Legend platform.
My need arose from a desire to hunt deer in Ohio, which has straight-walled cartridge regulations. I wanted a reliable, accurate AR-15 upper in .350 Legend, and the Aero Precision reputation seemed a safe bet. The allure of a complete upper – minimizing build time and compatibility issues – sealed the deal.
Out of the box, the upper exudes quality. The finish is impeccable, the ATLAS R-ONE Handguard feels solid, and the overall fit and finish are what one expects from Aero Precision. It’s immediately evident that this isn’t some cheap, slapped-together assembly.
Compared to a similar completed upper from Bear Creek Arsenal (which I had issues with jamming) and a build I put together using a Green Mountain barrel, the Aero Precision immediately impressed with its enhanced forging. This upper also comes with a much better warranty than Bear Creek, which is only six months. It’s a noticeable step up in perceived quality and attention to detail. The handguard is slim and feels much more rigid, which is important for mounting optics and accessories.
My initial impression was very positive. The upper looks and feels like a premium product; this is a sign it will perform as advertised. I was excited to get it to the range and see how it shoots.
Real-World Testing: Putting Aero Precision M4E1-T 16in .350 Legend Complete Upper with Flash Hider to the Test
First Use Experience
My first outing with the Aero Precision M4E1-T 16in .350 Legend Complete Upper with Flash Hider was at my local outdoor range. The weather was mild, around 60 degrees Fahrenheit, with a slight breeze. I mounted a Vortex Strike Eagle 1-8x scope and used a lower I already had with a mil-spec trigger.
The first few rounds felt different than a standard AR-15, with more noticeable recoil due to the larger .350 Legend round. The upper cycled flawlessly, and I quickly zeroed the scope. Accuracy was impressive, easily achieving sub-MOA groups at 100 yards with Winchester Deer Season XP ammunition.
There were no immediate issues, and the upper performed admirably right out of the box. I did experience a few failure-to-feed issues during the first 20 rounds, but the issue cleared up quickly. This can sometimes be attributed to the ammo used, a new magazine, or even the break-in period of a new upper, according to some user reviews.
Extended Use & Reliability
After several range sessions and a hog hunt, the Aero Precision M4E1-T 16in .350 Legend Complete Upper with Flash Hider continues to perform reliably. I’ve put approximately 500 rounds through it, using various .350 Legend ammunition, and any initial hiccups have completely disappeared. The upper now cycles reliably with all tested loads.
Durability is excellent. There are no visible signs of wear and tear on the finish or the handguard. I’ve bumped it against trees and rocks while hunting, and it’s held up without issue.
Cleaning and maintenance are straightforward, just like any other AR-15 upper. A quick wipe-down after each range session and a more thorough cleaning every few hundred rounds keep it running smoothly. Compared to my previous experience with the Bear Creek Arsenal upper (which constantly jammed and required frequent cleaning), the Aero Precision upper is a dream to maintain.
