Aero Precision M4E1 Threaded Assembled Upper Receiver
Aero Precision M4E1 Threaded Assembled Upper Receiver
The Aero M4E1 Threaded Upper Receiver features a new angular, machined design that sets it 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.
