Aero Precision M4E1 Threaded Upper Receiver, Assembled – FDE (BLEM)

This Aero Precision M4E1 Threaded Upper Receiver, Assembled – FDE  features a new, angular-machined design that helps it stand apart from standard mil-spec upper receivers.

Threaded to accept a standard AR15 barrel nut, this upper receiver features the same enhanced body profile as the M4E1 Enhanced Upper Receiver. It is forged from 7075-T6 Aluminum, precision machined to work with all mil-spec AR15 parts & includes a port door & forward assist, pre-installed.

The Aero Precision M4E1 Threaded Upper Receiver is designed to pair perfectly with the new M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.
