Aero Precision M4E1 Threaded Assembled Upper Receiver - Anodized Black

Aero Precision M4E1 Threaded Assembled Upper Receiver - Anodized Black - 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.
