This NVG Mounting System is unique that it provides two modes of operation. The G24 has the famous breakaway feature that provides the wearer the protection from neck or head injury. The first mode allows the mount to "break " from the base under a stressed condition such as snagged during fast roping or hitting a hard object when entering or exiting a vehicle or building. With this breakaway feature serious neck injuries and equipment damage can be minimized or avoided. The second mode allows the Universal NVG Mount to securely lock the mount to the base.
