Aero Precision Inc AR-15 9.3In ATLAS -ONE M-LOK Free Float Handguard

The ATLAS S-ONE is the newest addition to the Aero Precision handguard lineup. Machined from 6061-T6 aluminum, the S-ONE handguards are designed with size and weight in mind, making them the perfect option for lightweight builds. Aero Precision’s proprietary ATLAS attachment system provides a dependable and slim mounting platform while maintaining strength and stability.

Actual Handguard Lengths: 7.3", 9.3", 10.3", 12.7", 15" — measured from the receiver contact point to the end of the last Picatinny slot at the muzzle. Available in M-LOK profiles.

ATLAS

The Aero Taper Lock Attachment System (ATLAS) combines strength with aesthetics. It uses two mirrored tapered locking nuts to evenly distribute clamping pressure across a custom-engineered barrel nut via a turnbuckle screw. A ratcheting detent secures the system while providing positive registration during installation. The even clamping pressure avoids handguard distortion often seen with other systems.

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