Most Helpful Positive Review Nicely machined upper receiver
This Aero Precision upper makes the third different manufacturer upper I've tried. Cost wise it sits in the middle out of the three. The upper came packaged well and arrived with no machining blemishes or shipping damage. I have mated the Aero upper with a Anderson lower and the fit is amazing. The ...

Most Helpful Negative Review Product does not match description
The barrel that came in this configuration literally had no rifling in it. I'm not sure if this is an Aero quality control issue or a mistake on behalf of optics planet but it seems pretty garish. I sincerely hope it was just a one off mistake and they aren't sending out entire batch orders of blank...

Great Price

by Happy, Verified Owner from MA, United States Written on January 3, 2024
Received this and was impressed by its quality. It originally caught my eye due to the low price, but it shoots far better than I thought. Very happy with the purchase.

Aero complete uppe

by John C., Verified Owner from MA, United States Written on December 7, 2023
I had heard mixed reviews and honestly was more than happy with this purchase. Have a few hundred rounds through it and everything functions perfectly. Fast shipping received it a day earlier than expected.

Aero Upper

by cam, Verified Owner from VA, United States Written on July 6, 2023
Lightweight, solid feel, looks great, and super reliable. After about two thousand rounds of many ammo types, still runs like new. The cerakote is well done and doesn’t mark up easily. Everything was installed correctly and well secured.

Great product from Aero Precision
Pros:
  • Quality & Affordable
  • look & feel
  • Light weight
Cons:
  • None

AP M4e1 upper

by Silence214, from MI, United States Written on March 30, 2023
Solid upper, perfect length quality second to none. Well balanced and no issues with accuracy including 55, 62 & 77 gr. rounds. The mlok handguard is thin and ergonomic especially for C clamp hold. I wouldn't hesitate to purchase. For the price, there isn't anything out to match this upper.

Not for low IQ people

by DonaldBiden, from GA, United States Written on January 22, 2023
It clearly states it does not have a BCG or CH. Do not rate it low because you can’t read. The upper itself is awesome and a great value for the price. Machining is on point. This is a better product than the sloppy work done at PSA.

NOT COMPLETE

by Bleh, Verified Owner from NC, United States Written on December 23, 2022
This is NOT a complete upper. It doesn't come with a charging handle or BCG. Now I have to spend over $100 more to get the rest of the things I need to make my AR build work. What a WASTE. I 100% would have gotten something else if I would have known this was a lie and did not include everything you need.

Great accuracy

by PT, Verified Owner from IA, United States Written on November 7, 2022
Bought the 14.5" and mated it to a Geissele Super-Duty lower. Fit is great, no slop or gap. Shot about 3/4" MOA CTC with 75 gr HPBT. Gassing feels correct, cycled a standard full-auto bolt with a H buffer perfectly. Hand guard is as slim as it gets but still plenty ergonomic, and super light. Would definitely buy again.
Pros:
  • QUALITY made
  • Reduced weight
  • Very accurate barrel
Cons:
  • None
Best Used for:
  • High speed lead
Would recommend: Yes

Looks good, functions poorly. Hoping aero will make things right.

by JNash, Verified Owner from IL, United States Written on August 29, 2022
I have 4 other upper receiver assemblies and none are giving me the problems this one is. Failure to feed every time with a standard carbine weight buffer. Tried a different lower and heavy 5.4oz buffer, it would at least feed but still fail to feed occasionally. The bolt wouldn't lock open with either lower receiver or mag combination. I have reached out to aero hoping they can help.

great experience with OP

by boosh, Verified Owner from NC, United States Written on June 24, 2022
I initially ordered the 14.5 barrel, and opted to exchange it for a 16 barrel when I opted to not pin/weld, SBR, or brace it up but wanted to go straight rifle with no questions about it. And going though OP during the exchange process was really easy, the customer service was stellar. And they used a promo code I originally used, but for the new item. AND they allowed me to used an additional 10% promo that came out the day of the exchange(payment). It brought the price to the 14.5 which was awesome of them. I also grabbed an aero BSG, and Warhammer charger handle and everything arrived in great condition, parts all there.
