This complete upper includes the 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.
These pinned and welded 14.5" complete uppers feature a VG6 Gamma 556 that is permanently affixed to the muzzle providing an overall legal length of 16". If you've had a 14.5" build planned, but didn't want to deal with the hassle of getting it pinned and welded or being stuck with a specific configuration, then this 14.5 pinned and welded complete upper is for you!
