Most Helpful Positive Review Premium upper
I’ve owned multiple different brands of AR15 uppers over the years including; Colt, BCM, Palmetto State Armory, Daniel Defense and Rock River. This Aero Precision upper is my favorite. It is both aesthetically and functionally awesome!!! The rail is slim and ergonomic, and the barrel is 4150 CrMoV, so its premium material. The billet look this upper has is on point and it married to the PSA lower I put it on perfectly. There is actually less play between this upper and the PSA lower than there is on my Daniel Defense V7. Another great aspect of this upper is the price. For what you get it’s m...

Bent handguard

by Joe, from AZ, United States Written on August 2, 2023
I love aero products and haven’t had any issues before. This particular upper came with a hand guard that was bent sideways at the muzzle end. Other than that it seems good to go. I contacted customer support and they had me reach out to aero for a warranty claim.

Aero upper

by B, from FL, United States Written on December 14, 2022
I bought this upper and it ended up later getting the lower to match. I took advantage of the black friday deals and it came pretty quick. Ive put a couple hundred rounds through it with zero issues. It shot steel and brass ammo eith no problems. The handguard is very slim and light weight for carrying or all day training with. Aero makes great products so you cant go wrong getting one.

Excellent purchase

by Johnny, from NJ, United States Written on May 28, 2022
Very happy with this upper on my non nfa. Very light and accurate and fast shipping as usual. Completing this build has prompted a lot of curiosity among my friends and coworkers who are now looking wisely at the same upper.

Exactly what I was looking for

by WCGR, Verified Owner from OR, United States Written on April 5, 2022
I wanted a lightweight, minimalist 12.5 upper to build an AR pistol to add to my collection. This was to be my shortest, non-suppressed rifle that was going to contain an optic and a light, and maybe a grip on the list of furniture to add. Highly doubt I'll use an IR laser/illuminator, but it's nice to know there's a little rail in the front left if I need.

Fits my hand naturally, would easily see this as my new go-to.
