Aero Precision M4E1 Threaded Stripped Upper Receiver Black

The Aero Precision M4E1 Threaded Stripped Upper Receiver features the same profile as Aero's other M4E1 upper receivers but is threaded to accept a standard AR-15 barrel nut. Designed to match seamlessly with Aero's M4E1 lower, this upper gives you billet looks without the billet price. Does not include forward assist or port door.
