Nice Upper

by Upper receiver, from NC, United States Written on February 1, 2023
Great receiver the older gen MBUS flip up front sight is not compatible no issues with the rear recommend the newer MBUS front sight. Other than that I’ve put about 200 rounds through it so far I’ve had no issues with this upper receiver so far.

Well made upper for good price

by Junior, Verified Owner from AZ, United States Written on September 1, 2022
First AR pistol I built with upper and it’s worked phenomenal. Can’t wait to build a long rifle.I got the desert color and I love it. Super light weight and feels good in the hands. May upgrade the trigger later on but I see no problem with the one it comes with.
Pros:
  • Clean finish
Cons:
  • None
Best Used for:
  • ar pistol
Would recommend: Yes

Amazing quality upper

by David, Verified Owner from NM, United States Written on May 28, 2021
I received this right away after ordering which surprised me. The quality is astounding. Aero precision makes great parts. It comes unlubed for those that don’t know. The hand guard feels like grabbing a 12oz can. The front picatiny rail is a little small for a magpul front sight but still fits
