ATLAS S-ONE M-LOK FREE FLOATING HANDGUARD FOR AR-15

ATLAS S-ONE M-LOK FREE FLOATING HANDGUARD FOR AR-15 Reviews & Ratings

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. Aero's 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.

Actual Handguard Lengths: 7.3", 9.3", 10.3", 12.7", 15" -- Aero Precision rail lengths measure from end to end. This is the point of contact at the receiver to the end of the last picatinny slot at the muzzle.

Available in M-LOK profiles with 7.3", 9.3", 10.3", 12.7" and 14.94 (Actual Length 15") options.

ATLAS
  • 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.

Good looking and Light Weight

Solid handguard
Typical solid construction from Aero. Very light and fits great. A little tight on my lowpro gas block, but still works!

Svelte, light, and sturdy
I just finished installing this handguard, and it’s great all around. The quality of the machining and finish were excellent, installation was straightforward and secure, and it feels so thin and comfortable. Definitely one of the best lightweight handguards on the market.
