Shoots strait and must say the comfort of the for grip is well worth it. The hand guard is my favorite part of this upper. Other then that it is a basic upper the same as many other brands to me. I also like the numbers on the rail.

Purchased this Aero Precision upper chambered in 5.56 from a recommendation from a friend. He said all the products they make are of high quality and worth every dollar. As soon as my package arrived I was impressed by the packaging of the upper and when I picked up this complete upper I could tell immediately the high quality and fit and finish was amazing. The ATLAS S-ONE Handguard looks and feels amazing as well. I am still waiting for my other parts so that I can assemble my AR and finally take this bad boy to the range for some PEW PEW time! Thanks Optics Planet for having Aero Precision parts in stock, awesome price and for great service and fast shipping!

As described. Fits good to my lower. Seems to be well built. Very good looking upper. Just have to take to range and set some sights. Can’t wait to do some shooting. Would highly recommend if anyone looking for an inexpensive upper.

This is a nice looking, sharp shooting upper. Never shoot an AR15 before putting this together. Everything functioned perfectly with no misfires. I ran about 120 rounds of 223 at the range. My only compliant would be that this is listed as a complete upper with no BCG. I'm new to this, so i could be wrong, but not having a BCG is like selling a 80% upper. Would i recommend this? Yes i would.

I begrudgingly bought this upper to make my AR Pistol "legal" (it was until they changed the rules overnight) and not have to worry about ATF showing up wanting to violate me.Packaging?-Once the package arrived the first thing I noticed was how well it was packed. A++How's the rail?-The rail is SUPER slim! Not sure how I feel about the top non-rail, but it is light and very rigid. A-Fit and finish. -The forging on this thing is top notch. The finish is flawless and couldn't be happier. A++How does it shoot? -Okay, so I had very little expectations regarding accuracy. I was expecting 1.5-2.5 MOA and would have been happy with that. I was so shocked to see this thing is a TACK DRIVER! I was shooting .70-.80 MOA all day with Winchester 55gr ammo. This barrel outshoots my Geislee, Wilson Combat and DDM v7 AR barrels even with crappy ammo. This thing LOVES trash ammo! Shot brass and Wolf steel cased ammo with zero cycling issues. A+++Overall thoughts:10/10 would recommendThis lightweight, inexpensive, super accurate upper is a winner. Grab a BCG and charging handle as it is not included with this "complete upper", but for the price and performance who cares!

Forged upper that mates perfectly to a milled Seekins lower and would expect it to mate to any other quality milspec lower and would buy it again if it matched my next build type. I just slapped it on and did not separate the guard or barrel from the upper.
