The Aero Precision AR15 12.7″ ATLAS R-ONE M-LOK Handguard offers the perfect balance of lightweight design and durable performance.

About the ATLAS System
The Aero Taper Lock Attachment System (ATLAS) creates a dependable, distortion-free connection between the handguard and upper receiver. Dual mirrored tapered locking nuts distribute even clamping pressure across a custom-engineered barrel nut, while a turnbuckle screw and ratcheting detent ensure secure, repeatable alignment. This design eliminates flex and distortion commonly found in traditional clamp-style systems.
