Excellent questions WyoSmith.
I'm required contractually to remain in my residence for 6 years as a full-time resident--otherwise the city's housing authority will lower the boom on me financially. But that term is up in December. I paid 137 K for the place--in this economy and given the neighborhood, I'll be lucky to walk away with 30 or 40 K. That's a big hunk of money to take a huge loss on--but I will be gone one way or another by this time next year.
I don't need an AK--I already have an AR with M855 if I need it--but that's not the problem. I have to be sure of where each and every round goes when I pull the trigger--not an easy thing to deal with when a car pulls up with thugs who don't give a hoot about the law when they open up on your residence with an AK. I'm surrounded by homes and apartments. If you watch that video I posted above--the 7.62 was the superior penetrating round in an urban construction environment compared to 5.56 from M4/16.
I agree with your conclusions and courses of action otherwise.
