Do you plan to hunt with it?
If so when do you recall that when hunting you needed a 3rd shot?
If you needed a 3rd shot would it have made a difference?
If it were me just to satisfy my curiousity I would try the business card free-float, if it shot good 3-shot groups then hunt it that way, if not send it to someone who cares more about eye-candy then accuracy. But I would not mess with it other than that, it is a beautiful rifle and anything you do to that is not reversible will devalue it.
