    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.

    Aero Precision M4E1. 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 that gives the upper receiver a "billet look"
    • New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
    • M4 Feedramps
    • .250 takedown pin holes
    • Laser engraved T-marks
    • Includes port door and forward assist
