The Aero Precision M4E1 Threaded Upper Receiver stands apart from standard MIL-SPEC upper receivers, featuring an angular machined design. With the same enhanced body profile as the Aero M4E1 Enhanced Upper Receiver, this upper is threaded to accept a standard AR-15 barrel nut. Forged from 7075-T6 aluminum and precision machined to work with all Mil-Spec AR-15 parts.
NOTE: Port door and forward assist not included.
The M4E1 Threaded Upper Receiver is designed to pair perfectly with the Aero M4E1 Lower Receiver, offering a billet look without the billet price.
