From the manufacturer
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 and precision machined to work with all mil-spec AR15 parts. 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. New enhanced forging that gives the upper receiver a ""billet look"" New picatinny profile that blend Mfg: Aero Precision
