Ah, but how!?
The Second Amendment is clear that the keeping and bearing of arms shall not be infringed
, and even the 'argument' that it only applies to the militia is circumvented in many states due to the State Constitution having verbiage similar to the militia consists of all able bodied males 16 to 45
.
If you take that words of the 2nd Amendment seriously and literally, then the entire 1934 NFA should be an interesting historical footnote - a law that was tossed out in the 1930s for being unconstitutional.
But the government doesn’t, and they have the resources to investigate us, find and detain us, put us on trial and jail us (or worse). So, while I agree with you on a theoretical basis, and fight to make theory into practice at every opportunity that I have, I have to sometimes bow to the practical. NFA items are one of those times - the fed.gov takes that stuff VERY seriously.
