You crack out that un-registered rifle and even if you defeat the home invaders (or whatever), you are now guilty of a Federal felony (possession of an AW). How much prepping do you think you'll be doing in a Federal pen? Can you defend your family from behind bars? How will your savings be holding up after 10 years with no income, and having spent 100k on legal fees?
OK so if I took the risk of not registering my "assault weapon" Why would I then use it as my HD weapon? Especially when its common knowledge that the police will confiscate any weapon used in an incident. I would imagine that anyone smart enough to prep
for the AW ban would be smart enough to not expose himself that way.
Try a different scenario to make your point
