It is currently prohibited......so in short it is impossible for you to get one. However Spacesaver is right that it is in a big legal battle right now but there is no end in sight anytime remotely soon.
If Henderson wins the appeal, pretty much all of the guns deemed to be "variants" of prohib guns will be reclassified according to their technical specifications, not what they resemble cosmetically.
We will still have to challenge each decision.
Holy crap, a GSG5 thread that doesn't end with just a 'prohib, move on'
