at 300 blackout upper

by GRC, from OR, United States Written on November 10, 2023
as a career law enforcer officer i can’t tolerate any weapon that malfunctions. This ran perfectly right out of the box. Smooth feeding and straight shooting .

One piece upper

by Cave, Verified Owner from LA, United States Written on March 28, 2023
One piece upper receiver only fits an Aero handguard. I have large hands but this handguard is huge. It's as fat as a quad rail and isn't This one returnable. The top front of the handguard has a 5 slot proprietary pic section that is screwed into the handguard. What a dumb design. Although there are M-MOK slots they start too close to the fixed section which prevents mounting a pic section abutting the front without modification. Real estate is precious on a short handguard. I have purchased a lot of Aero parts in the past but this design has turned me off to their stuff.
Pros:
  • Sturdy
  • Looks nice
Cons:
  • Terrible design
Would recommend: No

great upper for AR builds

by UTG35, Verified Owner from AL, United States Written on December 5, 2022
This is a great upper. Super light weight and pairs well with an Aero lower. I put this on an Aero I’m going to hunt with. The hand guard is about double the size of the Atlas model. Price on OP was cheaper than any other website I could find. I’ve always had great product with anything Aero Precision.

Great Aero Upper

by Bruda, Verified Owner from WA, United States Written on July 18, 2022
I really like the 10 in AERO PERCISION UPPER. The hand guard is lightweight and big. It makes the pistol feel great not to small like your hands getting close to muzzle. I did a barrel break-in and cleaned it after every shot for like 20 rnds. It's a laser beam at 150yrds . My only grip is it looks like the barrel is not dimpled( set screws looks flush . ) i may not get a center set if I change out to a AERO Adjustable gas block. but a ABSOLUTELY GREAT SHOT. does not feel over gassed or violent to shoot/train with. Recoil is nominal. 300AAC is a great pistol, hard hitting ROUND. Optic planet is a great company to work with fast and reliable. THANK U OP
Pros:
  • Beautiful and light weight
Cons:
  • None
Best Used for:
  • Hunting - training

Second to non

by Dathan, from IN, United States Written on June 29, 2021
Aero did an amazing job making a quality ar upper for almost any task I am building this for deer hunting and varmints but to each their own. The packaging was great came in a nice padded cardboard box that was in another padded box, but prices have been getting high so it’s great that optics planet has been keeping the prices really low which is super rare right now. Over all an amazing product that will be bought again. �
Pros:
  • American made
  • Price and quailty
Cons:
  • non
Best Used for:
  • hunting
  • compeition
  • Home defense

Fine quality, great fit and nice features

by AR-noob, from WA, United States Written on January 3, 2019
This took a long time (FDE was longer) to arrive due to availability and is in the mid price range, not the cheapest but not the most expensive. It was worth the wait, this is high quality and runs very nicely. Dropped in the other Black Friday spoils to make a new rifle - an Aero Precision BCG and Geissle super charging handle, a Primary Arms red dot to complete the upper. Assembled an Aero Precision lower with a CMC single stage trigger and Magpul furniture and headed off to the range. The red dot zeroed in nicely and was soon dropping rounds in less than 1" circle at max range ~40 yd for initial indoor sight in, will see how it does at 100+ later on. I think this is the price/value sweet spot for 5.56/300 uppers.
Pros:
  • Quality
  • features
  • Fit
  • QD attachment points
Cons:
  • expensive - but worth it
Best Used for:
  • Target & Hunting
