I think the $200 tax stamp is enough to consider on its own, let alone the rest of it. The tax stamp limits the market to those who can afford an extra $200. At its inception it definitely did make those items available to privileged people. Inflation has made that less of a factor. But that does not rescue the logic of claiming that it’s okay because it’s not that much. It’s still enough to make it cost prohibitive for a lot of people.There is more to the NFA to consider than just a $200.00 tax. One has to keep the item available for inspection by ATF and one needs permission to take the item out of state. There may be other restrictions of which I'm not aware.
