Most Helpful Positive Review M4e1 Rocks!
I purchased the 16in Mid Gas Barrel and could not be happier. This upper is built to the likes of more expensive brands. Optics Planet.com actually beat the price I had found this upper on other sites including Aero Precision. If You are looking for a high quality build at a awesome price look no f...

Most Helpful Negative Review Nice but had some issues
First shots on a range and after the 2nd bullet the gun refused to cycle the next round, took it into a gun professional and he took it apart, found the gas tube was miss aligned and the gas block as well in opposite directions.

Excellence, even on a budget

by Andy R., Verified Owner from VA, United States Written on May 17, 2024
What a fantastic upper at a budget friendly price. I am so glad I decided to purchase this upper. I got the black 15” M-LOK hand guard version. Fit and finish is superb. Some reviewers mentioned that the hand guard was too thick, but if you shot and qualified with the military issued M16 or the M4 as I did for 10+ years, the diameter of this hand guard feels great. I have medium size hands and this is no problem for me to grab on to. This upper has made me an Aero Precision fan.
Pros:
  • Fit and finish
  • free float barrel
  • Aesthetics
  • QD points
  • m lock
  • continuous top picatinny rail
Cons:
  • wish I got this sooner
Best Used for:
  • Home Defense
  • Training
  • looking scary
Would recommend: Yes
