AR-15s
I have a 9mm CZ Scorpion and a Rattler that can shoot 300 blk out and 5.56. They have been very reliable. I prefer these guns for the folding stock and portablity. I have always stayed away from AR 15s because of the non folding stock. But if AR15 is what you like then that's what you'll get. Transfer fees are only 40 bucks.
