The AERO PRECISION M4E1 Threaded Assembled Upper Receiver features a new angular machined design that helps it stand apart from standard mil-spec upper receivers. This upper receiver features the same enhanced body profile as their M4E1 Enhanced Upper Receiver but is threaded to accept a standard AR15 barrel nut. It is forged from 7075-T6 Aluminum, precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed.
The M4E1 Threaded Upper Receiver is designed to pair perfectly with Aero Precision's M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.
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.
