The ATLAS R-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the R-ONE line of handguards are designed with size and weight in mind, providing the perfect handguard for your lightweight build. 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.

Available in KeyMod and M-LOK® profiles with 12″ and 15″ options (7″ and 9″ options coming soon).


The new Aero Taper Lock Attachment System (ATLAS) is both functional and aesthetically pleasing. It features 2 mirrored tapered locking nuts that provide evenly distributed clamping pressure across a custom engineered barrel nut with use of a turnbuckle screw. A ratcheting detent further secures the design while providing positive registration during installation. By design, the even pressure of the ATLAS system avoids distortion of the handguard often seen with current applications during installation.

All hardware mounting parts are included with the purchase of an ATLAS Handguard.

    Great service from BKing’s as usual. I am a big Areo fan and have been impressed with their slimmer rails. I do like the full top rail. Very Good quality at a decent price. What more can you ask for.
