West Texas's Review of Aero Precision M4E1 223 Remington/5.56 NATO Enhanced Upper Receiver

Looking at the reviews of people having issues with the barrel nut and its associated tool that Aero includes had me a bit anxious. This build is now my 10 year old grandsons varmint rig. We chose the Proof Research 22 inch carbon wrapped 22 Nosler caliber for it's light weight, low recoil and no wind or hold overs out to 300yds. I must say my 10 year old must be a superstar because during this build the only thing he let me do was secure the action block in the vise. I'm not sure if Aero redesigned the barrel nut tool or some people are more "ham fisted" than I realized because even heating the action with a heat gun on low so the Proof could be slid in without fuss all the way to torquing the barrel nut to 60ft.lbs. was accomplished by a very thin 10 year old.
Pros:
  • It's fit and rigidity are unparalleled
Cons:
  • Give me a minute I will think of something. Nope nothing yet
  • Give me a minute I will think of something, nope nothing
Best Used for:
  • Any and all AR builds
Would Recommend: Yes
