Truck Gun Options

I am looking for a good truck gun to buy. I know the options are pretty much endless but I would like to add a couple stipulations to meet my personal preferences. I'm open to any advice and new ideas, but would prefer to receive feedback on guns you have had first hand experience with.I would either like the gun to be broken down into pieces and easily reassembled in seconds. Or have a foldable stock so that that it can easily fit into a book bag.I would like the cost for the gun itself to be as low as possible because it is a truck gun and would spend the majority of the time not with me, putting it at a higher chance of being stolen.I am not looking for a small caliber rifle such as a .22 but rather a pistol carbine or larger. It would meant to be a medium range no frills gun that needed only marginal accuracy but 100% reliability.I am aware of many different ideas such as an semi-auto uzi or Kriss vector but the price is generally above $1000. AK47's are also a viable option but even low grade options are around 700 dollar range.I would like to hear if anybody has had experience with Kel-Tec sub 2000 gen 2, the TNW Aero Surviving Rifle or if there are options I am not aware of.Also apologies for misspelling and and grammatically incorrect sentence structure. via /r/CCW http://ift.tt/2kYDHMM
