ATLAS S-ONE Handguard

The Aero Precision ATLAS S-ONE Handguard is engineered for weight savings and performance. The Aero Taper Lock Attachment System (ATLAS) uses two mirrored tapered locking nuts to evenly distribute clamping pressure across a custom-engineered barrel nut through a turnbuckle screw. A ratcheting detent locks the handguard in place, ensuring proper alignment and long-term stability.

The minimalist S-ONE design removes unnecessary material without compromising durability, making it ideal for compact AR15 and M4E1 builds.
