Copy that anon. Required for any firearms period? Bummer. Not to suggest breaking the law, but it's extremely easy to make your own single shot slamfire weapons in any caliber you choose with basic handtools and handyman level skills. Youtube is loaded with videos.
A CB radio is also good for monitoring local situations. Local truckers are always gabbing (channel 19 in most areas) and if you can hang here at Q Research with all the BS, you could certainly deal with the truckers…lol. An Imax 2000 antenna mounted outside, a length of coax, a basic cobra 29 CB and a 10 amp power supply will set you back a couple hundred bucks.
