Product Info for Aero Precision M4E1 16in 5.56mm Complete Upper Receiver with Flash Hider

The Aero Precision M4E1 16" Complete Upper Receiver is a one-piece design combining the handguard mounting platform with the upper itself. This is a streamlined design that only needs eight screws to mount a free-floating handguard, making these AR15 Upper Receivers a more robust, durable system that you can count on. This complete upper receiver even comes with an A2 flash hider and Picatinny rails, so you are immediately ready to mount optics and take it to the range after installing it on a lower receiver.
