Nope, I have pro version but I have the Simlab P1 and I know how it is made, the Ultimate will fit perfectly, no problem.
Oh right, thought you were replying to Joe.
My understanding is the sport and pro will fit on the mige mount.
The ultimate is said to fit on the AKM mount?
I think the plan from GD was that the resellers will include the mount with the SC2?
