The FN® MWM is strategically designed to cater to the dynamic demands of the battlefield, allowing for swift adaptability. It's tailored for both ground and naval platforms, with a unique weapon interface that can be modified in mere minutes to accommodate various weapon calibers.

These range from the hefty 12.7x99mm NATO (.50 Cal) machine guns like the FN® M2HB-QCB to medium ones like the FN MAG® 58M/infantry and FN® M240, right up to the 40mm MK19 AGL grenade launcher.

This state-of-the-art mount has been meticulously crafted through a partnership between FN Herstal and FNH UK. It incorporates a hydraulic buffer system to guarantee optimal performance irrespective of firing angles or conditions. Notably, the mount is entirely mechanical, eliminating any reliance on the carrier's electrical power. It's also compatible with a myriad of additions, from ballistic protection to link and case collectors.

Its versatility extends to deployment possibilities. While the FN® MWM is fit for both wheeled and tracked vehicles, its naval counterpart, the FN® Sea MWM, is adept for challenging maritime conditions.
