Zigsta,
It definateley looks as though it will be, but I haven't seen one in the flesh, however with three suction cups it must be. Also, I do not know what fitting is supplied with the G-Force mount although I suspect that what ever it comes with you will be able to purchase an apropriate coupling for the 496.
The single suction cup RAM mount for the 496 is reasonably robust, but I did find that on ocassion it would fall free, which is not ideal. If I recall correctly, RAM also do a double suction cup version and it may be more apropriate to purchase this one.
What machine are you planning on installing it into?
