The Atlas S-One is designed with size and weight in mind. Aero's proprietary Atlas attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability. The 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.
