Aero Precision've always made reliable and high-quality products. I love M4E1 upper for its performance and design
Aero makes great stuff! The m4e1 upper looks and feels very nice. Will be using them again on my next build for sure!
Just got my aero m4e1 upper, its awesome! Great fit and finish, will be buying another one for my next build!
Great upper, aero makes good stuff!
Real nice upper, aero makes great stuff!
Finish matches perfect to my spikes lower with just a little wobble. Great looking receiver. Super fast shipping and the best price by far
The M4e1 upper was delivered in 2 days and I saved %30 thanks to the bullet point rewards! I paired it with a spikes lower and the finish is spot on but does have a little wobble. The "billet look" separates it from standard uppers with crisp edges and a great look. Would highly recommend this product and am going to pick up a matched set next.
Nice upper at a great price and aero has always been of quality to me.
Uppers are pretty standard, however Aero has made a great looking product! I especially love the threaded pin for the forward assist. It was easy to remove so I could cerakote the rest of it!
The quality of the receiver I got--after waiting a long time for it to come back in stock--is phenomenal, but what I can review about the site is how quickly and easy the process was to purchase it. Combined with the awesome "Bullet Points" and I'm ecstatic I was able to get the upper for a great price. Will be camping out on the site henceforth!
Amazing finish and such a good upper!
ordered this because of the chiseled look and was not disappointed with aero quality, also 1800G&A shipped quick. highly recommended
