Personally, I wouldn't have it re-parked. Most of the time, you'll just end up with a little scuffing, and no real damage to the finish. My rifles are working rifles and they get pretty beat up.
If you want it to be as asthetically pleasing as possible (it is afterall, a battle rifle), go ahead and choose the re-park option. But, for the money, you may just want to get a new barrel.
Pricing is HERE
If you have us swap FSB (using your new FSB), cut, thread, install Phantom, and re-park - you're looking at $165 + actual return shipping. Well on your way to a new barrel.
Just food for thought.
