johnchip's Review of Aero Precision M4E1 Threaded Assembled Upper Receiver
I bought the Aero Precision M4E1 Threaded Assembled Upper Receiver for a new Aero Precision M4E1 Build. It's a great upper receiver at a really good price especially on sale. Can't go wrong with Aero Precision parts. I've used them many times before and will certainly use them again in the future. I can definitely recommend this assembled upper receiver.
