Description

The AAC HUB2K is a direct-thread suppressor developed as an update to the M4-2000 legacy using DMLS 3D-printing technology for key internal components. The design emphasizes reduced weight and improved strength while using oversized baffles to help lower backpressure and minimize end-cap strikes on short-barreled rifles. The unit is configured for direct-thread mounting and retains HUB-compatible rear interface options.
