I have a few questions about the M4. I have been in the market for a good new shotgun and I ran across this amazing weapon. I have tried to obtain this from a local bass pro shop and several others in other parts of the south. I'm very new when it comes to the real guns law, I was told this would be a tactical weapon and it might require a different kind of permit to own. Really looking to know what I need to do to really get this M4.
