The Aero Precision M4E1 Threaded Upper Receiver (APAR700201C) 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 and precision machined to work with all mil-spec AR15 parts. The M4E1 Threaded Upper Receiver is designed to pair perfectly with the M4E1 Lower Receiver, giving you a billet-looking receiver set at a fraction of the billet price.

- .250 takedown pin holes
