Aero Precision AR15 Atlas S-One M-LOK Handguard FDE Cerakote


The ATLAS S-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the S-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 7", 9", 12" and 15" options.


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.

    Got for FDE Stripped Lower KE MK3

    Posted by WWSD Fan 2020 on 6th Feb 2020

    This new iteration polymer project in FDE coming 2Q has my name on one. Got this in 12" M-LOK to nestle into place. Not offering the built rifle in FDE just black so I'm building my own. Can't wait. This length just covers the gas block of the mid length gas system.

    Awesome fit and finish....

    Posted by Travis on 10th Dec 2019

    I can't stand full top rails anymore, I don't need them. Aero coming out with this was a blessing. Fit and finish matches their FDE upper/lowers perfectly, and mate up with them with solid lock-up. Nice and slim, so lightweight. Going to be my go-to handguard for the near future.
