ATLAS R-ONE Handguard

The Aero Taper Lock Attachment System (ATLAS) combines innovative function and a sleek design. It uses two mirrored tapered locking nuts that apply even clamping pressure across a custom-engineered barrel nut via a turnbuckle screw. A ratcheting detent secures the handguard and provides tactile feedback during installation. This system ensures even pressure, preventing distortion common in traditional handguard mounting methods and guaranteeing a secure, repeatable fit.
