MF11 AirBuffer Bundle

MF11 Air Buffer Bundle combines the MF11 (FMJ-05) full-face gas mask with the KB3D Air Buffer, providing a complete configuration that allows the Air Buffer to be used without requiring additional mask modifications.

This bundle includes the required components to convert the front MF11 valve for NATO40 compatibility, preparing the mask for use with the wider NEXUS modular system. A blocker insert is included to shut off one of the mask’s valves, ensuring correct airflow routing when the Air Buffer is installed.
