Flawless Review by Kevin

This was my first AR15 build. I built an all Aero AR (minus furniture and trigger) and I have had the rifle for over a year now and never had any firing/cycling issues. The gun works flawlessly and is also one of the smoothest shooting ARs that I have fired. I will only but Aero Upper and lower parts now. (Posted on 11/25/2016)

I bought the 18" .223 Wylde complete upper to put on an Aero lower I built. Fantastic quality and shoots better than me. (Posted on 11/2/2016)
Great upper! Review by whispershot

This is an awesome upper. The barrel (because of the 4150 and the QPQ treatment) is of the highest quality. I just received this upper a couple of days ago, so I've only had a chance to shoot it at 25 meters so far. At that short distance, I can put rounds in the same hole all day long. I can't wait to see what the accuracy is at 100m; I anticipate a sub MOA rifle. The price of this upper is a steal considering it's high quality. I will be buying more AERO parts and rifles. The upper is a little heavy, but I wouldn't trade the weight for the quality. Awesome upper! (Posted on 5/7/2016)

Top notch upper. I also purchased the nickel boron bcg to go with it and could not be happier. The only complaints I've read about aero was the time it takes to process the order and ship. My concerns were put to rest , I received my order in 5 business days with the 2 day usps shipping option. If you are considering buying something from aero, do it. You won't be disappointed if the quality and precision of my upper and bcg are any indicators of quality throughout their product line. (Posted on 2/14/2016)
Amazing quality Review by Armando

I just got my complete upper today. I ordered the 18" 5.56 Black M-Lok upper for a new build. It was hard finding what I wanted in stock but once it became available I purchased it. I had also considered buying all the parts and assembling my own but it was going to end up being a whole lot more expensive than the complete package they offer here. This is such a good deal.

The upper is built to quality standards. It fit my 80% lower perfectly with no lateral play. The action is smooth and it shoots true. Took about 10 minutes to get it zeroed in and I've put 100 rounds in the black out to 500yds since.

I can't say enough good things about this upper, and the company all together.

Thank you,
Armando O. (Posted on 1/28/2016)
