Like Goose and Tac Tech said, either an XCR or a Swiss Arms would do you well. Neither is a cheap option though. There is also the Tavor, but again that isn't a cheap go.
Maybe an SU-16.
And you can store every gun you own at home. Be is NR, Res, or Prohib. No gun that I know of requires you to store it in a specific location other than your home. Just follow storage regs and you are fine.
the swiss arms has the added thrill of a possible reclassification to prohibited!
