Functionally the same as the standard AR15 upper receiver, but with an angular profile of the popular M4E1 enhanced upper. This is a perfect match for that billet look, especially when paired with Aero Precision's M4E1 lower and when you want to build with the rail of your choice that does not mate up on the enhanced version.

NOTE: This part features a colored anodized finish. These finishes are held to different aesthetic standards than parts finished in black anodizing or Cerakote. By buying this part, you understand that the color of this part may not exactly match what is visually shown on the website, and that the part may also differ in shade when matched with other parts of the same color/finish.
