ATLAS S-One Handguard

The new Aero Taper Lock Attachment System (ATLAS) is functional and aesthetically pleasing. It features 2 mirrored tapered locking nuts that provide evenly distributed clamping pressure across a custom-engineered barrel nut using 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.
