About the ATLAS System

The Aero Taper Lock Attachment System (ATLAS) provides a secure, repeatable, and distortion-free mount. Its dual mirrored tapered locking nuts evenly distribute clamping pressure across a custom-engineered barrel nut, while a turnbuckle screw and ratcheting detent ensure precise alignment and long-term durability. This system prevents handguard deformation during installation and enhances overall stability.
