Excellence, even on a budget - Aero Precision M4E1 AR-15 16in 5.56 Mid Barrel Complete Upper Receiver with Flash Hider

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.
