Dirty's Review of Aero Precision M4E1 16in .300 Blackout Barrel Complete Upper Receiver with Flash Hider

Love this upper for the price. Put it on an old Bushmaster lower and feeds flawlessly. I’m using bulk mass produced off brand .300 and haven’t had an issue yet. Would definitely recommend.
Pros:
  • None
Cons:
  • None
Would Recommend: Yes
