Threaded High-Quality Upper Receiver To Make Your AR Build Stand Out

The Aero Precision M4E1 Threaded Assembled Upper Receiver is a bold new offering from Aero Precision that 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 the 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.
