This complete upper includes Aero Precision’s new ATLAS R-ONE Handguard on their billet-style threaded M4E1 upper. 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.
The proprietary ATLAS attachment system is a very durable and an extremely dependable mounting platform that provides a trim profile without sacrificing the strength and stability customers have grown to love from Aero Precision handguards.
This complete upper does not include BCG or Charging Handle.
