With all due repect, as only you can determine your financial restraints, I would strongly encourage you to try to extend your buying power closer to 20K (sell some stuff, relatives,etc) and get an M16 type weapon. At that price point more than likely a converted AR15. Why:
1-parts ALL over the place and will be more quite a while.
2-Get a bad round, the registered lower seldom gets hurt.
3-From the basic M16 you can get into: 9mm....45ACP...300BO....beltfed 5,56....22lr,,,,5.7 with the mag-on-top setup...who knows what else is coming down the invention road.
Careful shopping, aided by luck, will get you a converted AR15 at that price point.
Good luck!
