Aero Precision M4E1 Threaded 18" .223 Wylde Fluted Barreled Upper Receiver w/ ATLAS R-ONE Handguard


This complete upper includes the new ATLAS R-ONE Handguard! The R-ONE handguards are designed with size and weight in mind, while still providing plenty of real-estate to accommodate any attachment needs the end user may have. Aero's proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
