Most Helpful Positive Review Aero M4E1 223 wylde upper
I finally got some time shoot this upper on my latest build. So far it's been reliable and I am pleased with it's accuracy. I'm shooting 1 MOE groups with it so far with my 55gr handloads and 1x6 scope mounted to it. Although I like Aero's tan color for this, it's also my only complaint. It's a ...

Most Helpful Negative Review Failure to Eject and No Help from Aero Precision
Stay away from Aero Precision products! I bought this complete upper and had it for about 2 months before taking it to the range. The first 4 rounds failed to eject and I had to cycle it manually. The 5th round fired and jammed in the chamber. I had to damage my charging handle to get the jammed ca...

Aero customer support says 75+ grain ammo

by Woody, from TN, United States Written on August 4, 2022
I have this upper but haven’t fired it yet. I wrote a message to Aero Precision customer support because I had seen several reviews mentioning the rifle not cycling properly and I wanted to know if it’s a common issue. Their response (ticket number OMR-79910) was that the cycling issues are from people running ammo with too light of a bullet weight. They said they recommend at least 75 grain bullets for the rifle to cycle properly! I didn’t buy a 1:8 twist upper to only be able to run match ammo. I wish I had bought something different if it will inexplicably only work with high dollar ammunition.
Pros:
  • Looks good
Cons:
  • Have to run match grade ammo
Best Used for:
  • Blowing your money on 77 grain ammo
Would recommend: No

Nothing but trouble

by Rob, from OH, United States Written on June 26, 2022
There was loose steel in the barrel from manufacturing which lead to a casing being stuck in the barrel.

The bolt will not hold open on last round.

Customer support will not answer when you have problems.
Best Used for:
  • Weighing down in one's trashcan on a windy day
Would recommend: No

Aero precision upper

by Aero Upper, from VA, United States Written on March 19, 2022
Great value for this product. Has all the upper end components for the best price on the market. Stainless barrel in 223wylde, so far very accurate. Matched with hyper tap muzzle brake it is the softest shooting at I have ever experienced. Good for and finish and lightweight hand guard is the perfect size for medium size hands to c grip.
Would recommend: Yes

Aero Precision M4E1 .223 Wylde w/ ATLAS S-ONE Handguard Complete Upper Receiver

by Jryan, Verified Owner from NV, United States Written on March 26, 2021
The service and customer support from Optics Planet is the best the you will find in the industry. I added a VG6 Epslion muzzle brake in blasted stainless steal to the order. The muzzle brake matches the finish of the stainless steel barrel and looks amazing. I already have the same set up with a 18" barrel and it shoots sub MOA with good ammo. I expect this 16" barrel set up will shoot the same.
