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 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 a S-ONE Handguard.

    Pleasantly surprised at slim profile. Looking forward to using it in newest build.

  2. Kealohi Glanstein (verified owner)

    Product arrived as advertised with zero defects. Price was best I found anywhere, my only recommendation is an improvement on communication and processing shipping. Will be definitely buying again from B.KINGS

  3. Tj flores (verified owner)

    Very good quality and very fast shipping

  4. John Martiney (verified owner)

    Handguard did not fit my billet upper (Tradecraft) without filing the tabs that hook onto the front upper receiver. I.D. of the tab area had to be enlarged so as to slide all way in. I suggest a trial fit before you throw away box & packing!

  5. David Losaw (verified owner)

    Great price, fast shipping. Very pleased. Placed another order right away with the same results. A+.

  6. Antonio (verified owner)
