Aero Precision M4E1 Barreled Upper, 18" .223 Wylde SS Rifle Length Barrel, ATLAS R-ONE 15" M-LOK HG

This Barreled upper includes our 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. Our 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.
