This upper receiver features the same enhanced body profile as Aero’s M4E1 Enhanced Upper Receiver but is threaded to accept a standard AR15 barrel nut. The M4E1 Threaded Upper Receiver features an angular machined design that helps it stand out from standard mil-spec upper receivers. It is forged from 7075-T6 Aluminum and machined to work with all mil-spec AR15 parts. The M4E1 Threaded Upper Receiver is designed to pair perfectly with Aero M4E1 lower receivers, giving you a billet looking receiver set at a fraction of the billet price. This stripped upper does not include a port door or forward assist.
