The Aero Precision ATLAS R-ONE is a slim, lightweight Handguard with one of the most innovative mounting systems we've ever seen. Instead of the traditional delta ring/barrel nut mounting method, the ATLAS R-ONE utilizes Aero's new Aero Taper Lock Attachment System (ATLAS) technology: 2 mirrored tapered locking nuts that provide evenly distributed clamping pressure across a custom-engineered barrel nut. By design, the ATLAS system avoids the distortion found with traditional mounting methods while maintaining the strength and rigidity you expect. That combination of lightweight design and ATLAS mounting technology make it the ultimate Handguard for lightweight precision AR builds. It's compatible with standard mil-spec AR-15 uppers, mounting is easy, and all hardware and instructions are included. Make the switch, and you'll never go back.
