A shotgun, especiallya qquality semi-auto although there's no refuting the inherent reliability of a pump (which is why I love my M3 Super 90's, best of both), can give you more versatile firepower than just about anything else that isn't measured in 10's of mm diameter. From quad-0 and 00 or #4 Buck to the many different types of birdshot, rifled slugs, sabot slugs, potentially less-lethal rounds, and the fact that you can load the weapon exactly as needed (ie 2-3 compressed sintered metal/copper powder breaching "slugs" followed by buck). Oh, and one big thing that I was trained to do is to always, always take advantage of any lull to top of the tank; unlike magazine fed weapons, you are able to reload constantly whenever you are not actively engaged, so going into a room/etc you will ideally always have a full tube.
I live in a suburban area myself, and if the need to disable a hostile vehicle presented itself, I would pass over my 338LM and grab a 12GA with some hefty slugs. I don't think I would be able to hit anything accurately, well, not any more than "frontal area hit", but with 8 3" sabot/rifled slugs into the engine bay, I think you would have to be really unlucky not to damage something or another.
Otherwise, I can see the utility in having a medium-length barrel bolt action, although Kali likely doesn't allow for suppressors(?)... A 700 action in an AICS or McMillan stock, 3-9x optic, 16" floated bull barrel threaded, and chambered for 300BLK would give you the ability to remain very quiet if needed, but a magazine change has you firing supersonic rounds that, while still a bit quieter with a can, trade that whisper silence for a significant amount of impact energy.
I think that in a situation like mine, at least (suburban, town on edge of 1mil plus pop city), quiet and out of sight is a far better approach than Rambo-ing it up...
and they only good AR's left are $$$. My family doesn't have alot of money right now so I'm trying to find a cheaper substitute for an AR legal in CA. Thanks
