About the ATLAS System

The Aero Taper Lock Attachment System (ATLAS) provides an ultra-secure, repeatable mounting platform. Its dual mirrored tapered locking nuts apply even pressure across a custom-engineered barrel nut, while a turnbuckle screw and ratcheting detent lock the handguard firmly in place. This precision-fit system eliminates handguard distortion and ensures consistent alignment through repeated use.
