Most Helpful Positive Review High Quality
Last personal defense weapon a man could ever need. Mated with M4 lower-No Issues. Tight fit with perfect alignment, great budget build. Quality product with outstanding design. Aero makes a lot of other products for other “big name companies” as well.
Most Helpful Negative Review Did not mate with Aero Gen 2 lower
Ordered this to go with my Aero Gen 2 lower. Was very disappointed that it did NOT mate with it. The front take down pin would not go in, appears the holes are not properly aligned. Tried and tried but it would not insert. I took the lower receiver and turned the bottom side towards me, I then align...

great product

Review by dylan on 13th of march 2024 review stating Great product, enough said...but if not here we go.This complete upper was everything I never expected and more. I originally wanted the 11.5 for my AR pistol build and got this due to the current problem with getting items. It was a perfect fit, and shoots super sweet!! Paired it with a complete Aero lower...then all I needed was the optics to finish out my build. I have all Aero components and sRead more about review stating Great product, enough said...but if not here we go.o do all my friends. High quality that never disappoints.

changed rating

by tro jansky, Verified Owner from CA, United States Written on December 29, 2023
originally rated this high, but had not actually used it yet do to too many things going on in life. finally added it to a working lower and have had nothing but problems. FTE, Double Feed, etc. No matter what bcg, no matter what buffer weight...the thing wont cycle flawlessly at all. I am not sure if its a mfg defect or what but I've built plenty of ARs and just never had this many problems.

So far, Aero's "name" means nothing to me. Have to now go through the hassle of going direct to mfgr because optics planet only has a 30 day return window. Not happy with OP either.

very nice product

by tro jansky, Verified Owner from CA, United States Written on October 19, 2023
Great price to value ratio. Great brand (aero).

Only thing I will change is putting an adjustable gas block…San that, would recommend. Handguard feels a little chunky but very strong.

Would definitely recommend. Fit fantastic on a psa lower!

Perfect for my build

by Flyingmark, Verified Owner from MI, United States Written on September 21, 2023
First of all I was looking for a class costly option and this upper far exceeded my expectations. The carbine length gas system is beautiful. I bought an aero adjustment gas block and put it on immediately. The dwell time on this is amazing and smooth and makes it crisp and lite shooting.

Aero 10.5" Upper

by Bryan, from IN, United States Written on August 4, 2022
I mated this with my pistol lower and went straight to the range. I was able to adjust my Trijicon MRO (2 MOA) to zero at 50 yards with 6 rounds and confirmed my 50 yard zero with 5 more rounds. I printed a 1" group at 50 which is fine with me for my setup. After that, I ran 90 rounds of 55gr M193 and a 20 round mag of 77gr IMI Razor Core. No malfunctions and all brass ejected between 3 and 4 O'clock. My bolt carrier group was pretty dirty after only 121 rounds and, if that is my only complaint, I'm pretty happy with this 10.5" upper.
Pros:
  • Light & Accurate
Cons:
  • May be better with an H2 buffer
Best Used for:
  • 200 yards and in

Upper Receiver

by T-Rex Arms Bob, from TX, United States Written on December 16, 2021
At the time I had two Areo Precision lower receivers. Needed two uppers then bingo, in-stock, send it. Now I have two complete Aero Precision AR-15's. Both rifles work perfectly fine with about 2500 rounds through them. These uppers are top notch, recommend to everyone.

Aero 10.5” Upper

by Greg, from MD, United States Written on December 11, 2021
Very happy with the look and performance of this 10.5” upper receiver from Aero. It ran flawlessly on my pistol lower with an H2 buffer weight and cycled all rounds without any stoppages. I liked it so much I purchased a 12.5” upper as well for a separate build.

Good quality, one setback

by Idahogunner, Verified Owner from ID, United States Written on March 25, 2021
Today I set up everything to finish my aero build. Everything looks great and time to take to the range. Only setback is the front picatinny rail will not allow Magpul Mbus flip up sights to function as the rail sits too close to the handguard. I wound up just leaving my front sight set in the up position but is a bummer I can’t have it out of sight when looking down my red dot. Overall love the weight feel and fit.
Pros:
  • Weight
  • Look
  • fit & feel
Cons:
  • Mbus sights do not work properly
