  2. Aero Precision M4E1 Upper Receivers - Threaded vs Enhanced

    M4E1 Threaded Upper Receiver vs M4E1 Enhanced Upper Receiver

These 2 receivers are nearly identical in every way except for how the handguard attaches to the upper receiver.

    M4E1 Threaded Upper Receiver

    M4E1 Enhanced Upper Receiver

    The M4E1 Enhanced Upper Receiver utilizes a one-piece mounting system for the handguard that is integrated into the upper receiver forging itself, rather than using the barrel nut as seen with more traditional upper receiver and handguard designs.
