Aero Precision ATLAS S-ONE Free Float M-LOK AR 15 Handguard

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 AR 15 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 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.

    Every time that I've ordered from... my orders...

    Every time that I've ordered from BRD my orders always arrive sooner than I expected. My latest order is no exception. I ordered a low pro gas block, gas tube and an Areo Precision free float handguard. All arrived in excellent condition. I most assuredly Will order from BRD in the future.

    Great quality!

    A little on the spendy side, but you definitely get what you pay for. A quality product backed by a quality company. Looks great and is comfortable to hold.
