Firing Hungarian AMD-65 7.62x39mm AK-47 Rifle

For a state such as Iowa, which doesn’t have any of the tight gun restrictions many of the more heavily populated states along the coastal time zones have, i was wondering what it takes to get a rifle chambered in .50BMG for a person with enough money for one. A friend told me you could put a .50BMG upper onto an ar15 lower, with it remaining classified as an AR15. But those uppers look to cost as much as the Vulcan Arms .50BMG, in the 00 price range, so i see no reason other than dodging laws to get the conversion instead of a dedicated rifle.

So if i went to my local privately owned gun shop, could i have them order me a .50BMG? Or is it a class 3 weapon? Could i just get the ammo, or is the ammo also subject to needing a license to purchase?
