For Sale, asking $200, no trades:


Aero Precision M4E1 Enhanced Upper Receiver


Color: Black


Condition: Like new, do not believe this has ever been used in a build


Barrel Nut & Wrench (photographed) are included. I do not have the original box for this receiver, but I can include the box for a different one.
