LB's Review of Aero Precision M4E1 Threaded 8in .300 Blackout Complete Upper Receiver with Flash Hider
This complete upper (minus BCG and charging handle) makes any build easy.
No worrying about gas tube length or type of gas block to install. It's all done for you by Aero Precision.
Accuracy is very good with constant groups.
The only issue I had was my failure to clean the packing grease out of the star chamber.
This grease collected powder reside and kept the BCG from fully going forward. I did clean the barrel before firing but forgot about the chamber. My bad.
After a though cleaning I've had flawless functioning.
This is my second upper from Aero Precision and both have been stellar products.
