The Lantac USA ADC Plan B Hub (brand part no. HUB-ADC-PB-1375-TI) is a titanium adaptor for Lantac’s Adaptable Core mounting system, threaded in the 1.375×24 pattern used by several large-bore suppressor mounts. Like Lantac’s other ADC hubs, it’s a modular front-end piece that lets the same mount body accept a different thread interface without buying a whole new mount. This Class 3 accessory is a mounting adaptor, not a muzzle device or suppressor on its own.
