Aero Precision AR15 M4E1 Threaded Assembled Upper Receiver – Kodiak Brown Anodized

NOTE: This part features a colored anodized finish. These finishes are held to different aesthetic standards than parts finished in black anodizing or Cerakote. For more information on colored anodizing, visit our Knowledge Center.

The M4E1 Threaded 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 our 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 our new M4E1 Lower Receiver, giving you a billet-looking receiver set at a fraction of the billet price.


  • New enhanced forging gives the upper receiver a “billet look”
  • New Picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
  • M4 Feed ramps
  • .250 takedown pin holes
  • Laser engraved T-marks
  • Includes threaded forward assist roll pin
  • Includes port door and forward assist

Note:  There may be slight differences in appearance between uppers/lowers & handguards.  We do our best to ensure the coatings match before shipping, but we DO NOT guarantee a 100% match or exchange products for this reason.  If you have an issue with colormatching/coating, your claim is with Aero Precision directly, not Arm or Ally.
